On OSX 10.5 with Xcode 3.0, whenever I build either the trunk or the py3k or 25 branches, I get a series of errors when setup.py tries to build the _OSA module. On OSX 10.4 it builds fine. Can anybody help? I don't even know what OSA is! -- --Guido van Rossum (home page: http://www.python.org/~guido/)
