People write 'packages' that extend/enhance the functionality of Perl. DBD-mysql is one such package to make it easier to access MySQL databases from Perl.
ppm (Perl Package Manager) is a utility to find and install such packages. Those commands I gave just located and installed (from a repository on the Internet) the latest version of the packages called DBI and DBD-mysql which the export_spells.pl script needs to function.
