Yeah, that really sounds like a great idea :)

First problem: 

Wrong version of perl. Won't work. 

Second problem: 

Digest::MD5.3pm.gz clashes with the file installed by perl included in
CentOS3.

Third problem: 

 (@INC contains: /usr/lib/perl5/5.8.0/i386-linux-thread-multi
 /usr/lib/perl5/5.8.0
 /usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi
 /usr/lib/perl5/site_perl/5.8.0 /usr/lib/perl5/site_perl
 /usr/lib/perl5/vendor_perl/5.8.0/i386-linux-thread-multi
 /usr/lib/perl5/vendor_perl/5.8.0 /usr/lib/perl5/vendor_perl
 /usr/lib/perl5/5.8.0/i386-linux-thread-multi /usr/lib/perl5/5.8.0 .)

.../site-perl/ is far down in that path, so every module living in there
won't get included, if there's a module of the same name somewhere
earlier in that path. And that is the problem here.

BTW: @INC in RedHat just sucks as there's no possibility to override
core modules in perl. The problem with that is upstreams @INC which is
exactly the same.
