New Perl 5.8 install breaks Fink

[brossow]

I recently installed Perl 5.8 per the instructions posted on this site for installing ClamAV wiith Exim. Everything was fine until I began the process of setting up the server as a PDC. Fink installed fine, but when I try to update-all, scanpackages, list, selfupdate, or just about anything else I get the following error:

[code:1:ba5f0bf4a1][mail:/Users/admin] admin# fink update-all
dyld: perl Undefined symbols:
_Perl_safefree
_Perl_safemalloc
_Perl_saferealloc
_Perl_sv_2pv
_perl_call_sv
_perl_eval_sv
_perl_get_sv
Trace/BPT trap[/code:1:ba5f0bf4a1]

Perhaps worse, after reverting to the old (v5.6) Perl, I still get get errors with fink:

[code:1:ba5f0bf4a1][mail:/] admin# fink scanpackages
dyld: perl Undefined symbols:
_Perl_get_sv
_Perl_getcwd_sv
_Perl_sv_2pv_flags
_Perl_sv_setsv_flags
Trace/BPT trap[/code:1:ba5f0bf4a1]

Any help? I [b:ba5f0bf4a1]must[/b:ba5f0bf4a1] get this PDC set up today, so I guess I’ll have to compile samba myself and then do all updates on my own as well. 🙁 However, if someone has quick suggestions I can find something else to do for awhile while praying that someone responds to this post.

After another hour of digging on the ‘Net for a resolution to this, I finally discovered that this is a known issue caused by Fink. Here’s the solution: http://archive.develooper.com/[email protected]/msg02447.html

Just in case the page I linked to would disappear, here’s the text of that message:

[code:1:f449a1a2de]perl 5.8.0 issue on Mac OS X w/ fink

SYNOPSIS:

The release notes for perl 5.8.0 indicate:

"Perl 5.8 is not binary compatible with any earlier Perl release,
XS MODULES WILL HAVE TO BE RECOMPILED!"

Mac OS X users that have fink installed may experience the
following error when executing certain perl operations (see ‘EXAMPLE’).

dyld: perl Undefined symbols:
_Perl_safefree
_Perl_safemalloc
_Perl_saferealloc
_Perl_sv_2pv
_perl_call_sv
_perl_eval_sv
_perl_get_sv

This error is separate from the similar dyld issue mentioned in the
"Mac OS X dyld undefined symbols" section of perldelta[1].

EXAMPLE:

The below is one example of how to reproduce the issue. There are many
other ways to reproduce it. I have experienced the same behavior when
attempting to "perl Makefile.PL" certain modules (such as CPANPLUS
below). CPAN.pm also exhibits the same behavior when attempting
certain operations after configuration.

root@localhost:/tmp$ perl -MCPANPLUS -e shell

CPANPLUS::Shell::Default — CPAN exploration and modules installation (v0.02)
*** Please report bugs to <[email protected]>.
*** Using CPANPLUS::Backend v0.035. ReadLine support enabled.

CPAN Terminal> o
Checking if source files are up to date
dyld: perl Undefined symbols:
_Perl_safefree
_Perl_safemalloc
_Perl_saferealloc
_Perl_sv_2pv
_perl_call_sv
_perl_eval_sv
_perl_get_sv
root@localhost:/tmp$

CAUSE:

The error is caused by the following sequence of events:

1 – a .bashrc (or other shell rc file) sources /sw/bin/init.[c]sh
2 – init.[c]sh sets PERL5LIB to /sw/lib/perl5
3 – /sw/lib/perl5 contains Storable (the only compiled perl module,
included by default, to my knowledge), and possibly other XS
modules. Since Storable is a compiled XS module that was compiled
with a prior version of perl that is binary incompatible with
perl 5.8.0 it will be necessary to recompile Storable
(see ‘RESOLUTION’).

FURTHER CONSIDERATIONS:

Fink stable currently includes the following six XS modules. If any
of these were installed prior to installing 5.8.0 you will likely
experience the dyld issue.

– DBD::Mysql
– DBI
– Digest::MD5
– MacOSX::File
– Storable
– Term::ReadKey

You will also experience the dyld issue if any other XS modules are
contained within the /sw/lib/perl5 directory. That is, XS modules
from fink unstable or another source.

RESOLUTION:

The following three commands will correct the above issue by removing
the current Storable and replacing it with a recompiled version. These
commands must be executed as the superuser. After these commands are
executed the aforementioned issue will be resolved.

mv /sw/lib/perl5/darwin/Storable.pm /tmp
mv /sw/lib/perl5/darwin/auto/Storable /tmp
fink rebuild storable-pm

It IS first necessary to do the mv’s, before the rebuild, since fink is
a perl script that explicitly adds /sw/lib/perl5 to @INC, and exhibits
the behavior mentioned above.

You will need to execute the above commands for every XS module that
is contained within /sw/lib/perl5.

Following the advice above solved the issue for me. I’m posting this info in the hope that this helps someone else! Wish this info had been posted here earlier….
