in reply to Setting build path for modules

You set the install path with --install_base resp. INSTALL_BASE. The CPAN configuration variables mbuildpl_arg resp. makepl_arg and the environment variables PERL_MB_OPT and PERL_MM_OPT can supply default values. If these are not set, modules are installed automatically into the appropriate place.

I have no idea how it could happen that you end up with both /lib and /lib64. Some information is lacking from you. Show the output of

    Though I'm not sure if that's the correct one since I found so many Config.pm in a lot of directories.

      Quoting your Perl configuration:
      -Dprivlib=/usr/lib/perl5/5.8.8
      -Dsitelib=/usr/lib/perl5/site_perl/5.8.8
      -Dvendorlib=/usr/lib/perl5/vendor_perl/5.8.8
      -Darchlib=/usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi
      -Dsitearch=/usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi
      -Dvendorarch=/usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi

      The problem stems from Redhat's practice of defining these divergent paths explicitly at compile time. I cannot fathom why, but probably they thought they had a good reason to do so. (Normally one only defines a common prefix.)

      Your Perl is very old and unsupported. You should get an updated package for your OS, or if failing that, simply abandon the installation compile your own current stable of Perl (as of now this is version 5.16.0) into a different prefix. Perlbrew helps you automate most parts of that.
