Subject: LibNeural on OS X: undefined symbols

Running OS X 10.2.4, trying to make use of Akimichi Tatsukawa's
LibNeural package.  I downloaded Swig 1.3.9 and built it from source
(it's the version listed on the LibNeural page as having been used to
test it), with no errors I could see.  The LibNeural package also
built with no errors, but when I ran the test scripts I got a whole
mess of undefined symbol errors like so:

ruby odd_even.rb
dyld: ruby Undefined symbols:

Has anyone run into anything similar on OS X or anywhere else for that
matter?  I searched the newsgroup but the only thing I found relating
to LibNeural was a release announcement.

Thanks,
