This is probably an issue with 2.12.7 to 2.12.10 as current. I haven't tested beyond 2.12.7 however. The AccessControl module; specifically the shared lib cAccessControl.so as built on an osx arch x86_64 is incorrect as the runtime expects i386. In most cases a knowledgable user will able to rebuild this library with something like: gcc -dynamic -bundle -arch i386
-I/Applications/Plone4/Python-2.6/include/python2.6 -I/Applications/Plone4/buildout-cache/eggs/ExtensionClass-2.13.1-py2.6-macosx-10.4-i386.egg/ -I/Applications/Plone4/buildout-cache/eggs/Acquisition-2.13.3-py2.6-macosx-10.4-i386.egg/ /Applications/Plone4/Python-2.6/lib/libpython2.6.a /usr/lib/libpython2.6.dylib -L/Applications/Plone4/Python-2.6/lib/ cAccessControl.c -o cAccessControl.so
Unfortunately in the above specific case I'm building against a standalone Plone instance which ships only with a static lib version of Python 2.6. So this doesn't work. This became an issue with Plone 4.0b5 as this is the first version to include Zope 2.12.7 egg. The 2.12.6 egg has the correct arch. The only remedy I can readily see is that however cAccessControl.so is built needs to be built specifically for the i386 arch and stuffed into the egg. -- Christopher Warner http://cwarner.kernelcode.com
