Thank you all for helping me!
Hypnos: I am using /developer libs to link; I recompile panda, because py2app choked on my last version; this is why i want to try out the compiler flag i mentioned, -headerpad_max_install_names. I want to build universal libraries and binaries, i used lipo to fold ppc and i386 files into universal binaries. I hope that the linker flag helps py2app…
