I want to use a program. But I receive error from my qube3

Can’t locate warnings.pm in @INC (@INC contains: . /usr/lib/perl5/5.00503/i386-linux /usr/lib/perl5/5.00503 /usr/lib/perl5/site_perl/5.005/i386-linux /usr/lib/perl5/site_perl/5.005 .)

Simple question: how to avoid the warnings.pm message and / or how to install the warnings.pm into the 5.00503 perl installation?

#!/usr/bin/perl -w

I need the -w to be able to start a cgi script.

Any people who can help?
