Perl MCPAN can’t write Makefile!?!?

In attempting to install SpamAssassin per Joel's article, I'm getting some problems with the perl CPAN installs. It says it can't write the Makefile and then fails all other steps past that. Yet it seems to write the file fine. I'm running perl with sudo and also after su'ing to root. I've even changed the ownership of the directories and files to root to be sure. This is all on 10.3 Server with XCode installed.
