We do some hackery to try to determine whether we are running 'normally' or from a standalone built with py2app, py2exe, bundlebuilder, macmillan, etc. (so we can look for resource files in the different places they finish up, rather than in their usual directory alongside the .py file). Part of this is in util.py / main_is_frozen() - where there was an explicit test for a 2.3 based path, specific to the OSX version. Because we wrongly believed we were "frozen". we looked in the wrong place(s). Not sure what the medium term fix is (long term I think it is probably setuptools as Ronald suggested earlier) - but there will be a short term fix in CVS soon, hopefully tonight, so if you have been wanting to move to Python 2.4 but were held back by PythonCard, you should be able to get that soon. Note there may be a delay of up to 24 hours before anonymous cvs access catches any updates. -- Alex Tweedly http://www.tweedly.net -- No virus found in this outgoing message.
