Actually, It looks like the second case to me, not the first. You've got a universal build with 3 archs, no a single i386 arch (you have a default snow leopard python install, right?) That is what I've got, and it builds and works ok when the python "defaults" are set to use 64-bit. If I change it to run a 32-bit python, I get a "Symbol not found" message (though not the same one as you). I spent a lot of time getting it to run on my Snow Leopard install. It worked eventually, but I never understood the details. My best guess (could be wrong) was this: - hdf5 is NOT set up for a universal build. For some discussion of this have a look here http://www.kyngchaos.com/macosx/build/hdf. So, by default it just build as one arch (I think the default is 64-bit). - Whatever arch it is built with will be the only arch it will work with in python. - So you need to match the 1 arch of hdf5 lib with the arch of the python you are running. You tried building 4 different times, but did you test each of this with both a 32-bit and a 64-bit python? ie: defaults write com.apple.versioner.python Prefer-32-Bit -bool no > python etc etc defaults write com.apple.versioner.python Prefer-32-Bit -bool yes > python etc etc If you already did this, then I'm stumped too...
