i'm having difficulty installing on os x. when running 'perl Makefile.PL', I get:

Installing all the default data files.
Checking WordNet::QueryData ... done.

Can't locate object method "version" via package "WordNet::QueryData" at Makefile.PL line 257.

obviously, there's a problem with my installation of Wordnet::QueryData, but it installed fine:

WordNet-QueryData-1.46 snider$ perl Makefile.PL
Writing Makefile for WordNet::QueryData

WordNet-QueryData-1.46 snider$ sudo make
Manifying blib/man3/WordNet::QueryData.3pm

WordNet-QueryData-1.46 snider$ sudo make install
Writing /Library/Perl/5.8.6/darwin-thread-multi-2level/auto/WordNet/QueryData/.packlist
Appending installation info to //System/Library/Perl/5.8.6/darwin-thread-multi-2level/perllocal.pod

and 'make test' shows no errors. as for the other packages, Text-Similarity installed fine. I wasn't able to install Wordnet-3.0 (a bunch of tcl package errors, but tcl-tk is installed), but i should only need the data from Wordnet, not the interface, right? or is that the problem? otherwise, any clues what the problem might be?
