I've run into a problem using mod_python under OS X Leopard: because the apache2 process runs in 64-bit mode, the python interpreter is forced into 64-bit mode, which breaks compatibility with any Python library with underlying C code. I suspect that adding a compiler flag specifying "-arch x86_64" to any gcc invocation would fix the problem, but I'd rather not do this package by package: I'd like to set one global parameter and be done with it. Apparently, I can add an entry to the global pydistutils.cfg file. However, I can't seem to find the appropriate parameter. The pydistutils.cfg file follows the nomenclature of command-line setup.py invocation, but I haven't found a C compiler pass-through parameter for setup.py. Does such a parameter exist? If I want to add a flag ("-arch x86_64", in this case) to the C compiler invocation, how do I pass that to setup.py? Thanks for any help, kieran hervold
