This is not an appropriate ticket for the Perl 5 core distribution's bug tracker, rt.perl.org.

Whatever DB/Meta.pm and Class::PseudoIxIIHash may be -- Internet search turned up nothing relevant -- they are not code distributed with the Perl 5 core distribution.  Only bugs in that core distribution are on topic for this list.

I recommended going to a Perl help site such as perlmonks.org.

Thank you very much.
