I'm not sure if this can be solved here but installing Perl Modules don't seem to affect @INC since I keep getting errors that look like this:
Can't locate File/ReadBackwards.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5) at post.cgi line 6.
BEGIN failed--compilation aborted at post.cgi line 6.
or
install_driver(mysql) failed: Can't locate DBD/mysql.pm in @INC (@INC contains: . /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5) at (eval 406) line 3, <FILE> line 3.
Perhaps the DBD::mysql perl module hasn't been fully installed,
or perhaps the capitalisation of 'mysql' isn't right.
Available drivers: DBM, ExampleP, File, Gofer, Proxy, SQLite, Sponge.

It's not a big deal if I can't solve this here though.
