If you want to use MySQL with Perl, you need to install the DBD::MySQL driver module. However, at the time of writing, this module was not available when I tried to install it via the ppm tool using ActiveState Perl. A broader search just reported:
ppm> search DBD-MySQL
Searching in Active Repositories
1. DBD-mysql-SimpleMySQL [0.5] (none)
If I can't find a module in one of the ActiveState repositories, the next place I look is at the Theoretical Physics of the University of Winnipeg website. If the module is available, it can be installed with just a one-liner. For ActivePerl version 8xx:
C:\>ppm install http://theoryx5.uwinnipeg.ca/ppms/DBD-mysql.ppd

Install 'DBD-mysql' version 3.0002 in ActivePerl 5.8.7.815.
