The configure flags look fine, although I on't use the 64-bit option myself. I use '--with-universal-archs=3-way --enable-universalsdk=/'. That one is usable on all systems running 10.5 or later, but doesn't support 64-bit code on PPC. Do you use ctypes? I'm pretty sure there are bugs in libffi for darwin/ppc64, although I don't know if these affect ctypes. I don't support ppc64 in PyObjC because libffi caused exception handling there (at least the last time I tried running on such a system). Another option that might be useful when you're experimenting is '--with-framework-name=NAME'. That allows you to rename 'Python.framework' to something else, which allows you to test if a new checkout results in a workable installation before you upgrade the real install. > > It's not that I plan to do this often, but I want a shell script that > installs everything I want.

I have a script that builds a lot of frameworks here: <http://svn.red-bean.com/pyobjc/trunk/pyobjc/build-support/build_frameworks.py>. The script builds debug builds of python for a number of architectures and python versions. Ronald
