Changes from previous:
1.33 Thu Aug  4 23:25:14 EDT 2011
    - move build_db() to separate .PL script so that module can be
      built even if Class::Accessor and other dependencies aren't
      available before Makefile.PL is run.
    - list GDBM_File as an explicit dependency, assome distributions
      like ActivePerl don't include it even though it is a
      core module.
