I'm trying to use connect to a mysql database and I read somewhere to use the DBI class. So, my program looks like this

#!/usr/bin/perl
#
use DBI;

but it dies right there on line 3 with this error..

Can't locate DBI.pm in @INC (@INC contains: /usr/lib/perl5/5.00503/i386-linux /u
sr/lib/perl5/5.00503 /usr/lib/perl5/site_perl/5.005/i386-linux /usr/lib/perl5/si
te_perl/5.005 .) at ./testrun.pl line 3.
BEGIN failed--compilation aborted at ./testrun.pl line 3.

So I'm stumped, I'm new to perl. Can anybody tell what I need to do?
