Jared,
  Koha/QueryParser/Driver/PQF.pm
has a use base qw(OpenILS::QueryParser) 
but unless you installed the OpenILS modules ( by installing evergreen)
that will not exist in your Perl lib path so you will be using an empty
class as the parent. There are a few other hardcoded references to yje
OpenILS tree in the QueryParser code.

Cheers
Colin
