Amavisd, OS X 10.2.8 Server

I have been struggling to get Amavisd to work on the mail server I have been setting up. I have Postfix working along with pop-before-smtp . I have followed the directions in this article Spam and Virus controls with Postfix. I have update perl to 5.8 and done all of the module updates indicated in the article. I have also installed the latest version of amavis_new hoping that would correct the issue. Consistently when I attempt to start amavisd I get: dyld: perl multiple definitions of symbol _crc32 /Library/Perl/darwin/auto/Convert/UUlib/UUlib.bundle definition of _crc32 /Library/Perl/darwin/auto/Compress/Zlib/Zlib.bundle definition of _crc32 Trace/BPT trap I can't seem to find a clear answer as to what is causing this, or what to do about it. Obviously there are problems in these two modules. . . Anybody seen this or have a solution?
