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.
