Ruby/Zoom, Yaz problem

Ok, I have successfully built Yaz and Ruby/Zoom on Feisty Fawn and OS
X/Tiger (Intel) in the recent past.

I’ve tried to do the same thing on Tiger/PPC and am encountering the
following problem when trying to <require ‘zoom’> from irb:

dyld: NSLinkModule() error
dyld: Symbol not found: _ZOOM_connection_search
Referenced from: /usr/local/lib/ruby/site_ruby/1.8/powerpc-
Expected in: flat namespace

Trace/BPT trap

I configured Yaz with --enable-shared and did everything that has
worked in the past, but this time it’s just not working. I’ve tried
hosing the Yaz install and rebuilding but that hasn’t worked either.

Can anyone help with this?
