This error says that perl looked in
/etc/perl
/usr/local/lib/perl/5.10.0
/usr/local/share/perl/5.10.0
/usr/lib/perl5
/usr/share/perl5
/usr/lib/perl/5.10
/usr/share/perl/5.10
/usr/local/lib/site_perl
and the current directory
for the module and could not find it. This means that either
you do not have that module installed or it is installed in
a directory perl does not know to look in. You can use the
environment variable PERL5LIB to tell perl about other directories
to look in.

PERL5LIB is an environment variable. It holds a list of places to look
for modules in the same way PATH holds a list of places to look for
executable files. It is only necessary if you install modules in a
non-standard location. For instance, I install modules in my home
directory to avoid having to become root and to make uninstalling
them easier, so I set PERL5LIB like this in my ~/.bash_profile:
export PERL5LIB=~/perl/lib/perl5/site_perl
