Hi
toronto75,
Did you install the ppm available from http://theoryx5.uwinnipeg.ca/ppms ? It looks to me that it may have been built against a static build of the YAZ library - and if that's the case, then the version mismatch you've come up against will not arise.
If you want to give that particular version a go (assuming it's not the one you've already tried):
ppm install http://theoryx5.uwinnipeg.ca/ppms/Net-Z3950-ZOOM.ppd
Cheers,
Rob
