Mike, your Perl installation typically comes with "perldoc"s, which is a bunch of great perl documentation. On *nix, you can start by doing
perldoc perl
and that lists all the different topics covered in the perldocs. In that list, you see "perlmod", "perlmodlib", and "perlmodinstall" - my guess is you are looking for "perlmod".
FYI, the DBD modules, DBD::mysql included, come with a README and/or INSTALL that explains how to install it. You didn't mention DBI, but you'll also need the Perl DBI module. I seem to have a mental block because I can never remember which one has to be installed first - I think DBI needs to be installed first, then DBD::mysql. And I'm sure you already know this, but just on the off chance that you don't...you need to have MySQL installed before you install DBD::mysql.
Also, the DBI and all the DBD modules come with great documentation - after they are installed, you can do
perldoc DBI
to get great info on DBI - this is a *MUST* read. And
perldoc DBD::mysql
will tell you how to use DBD::mysql to connect to a MySQL database - also a *MUST* read.
HTH.
