Hi Edward,
A solution is posted at http://stackoverflow.com/questions/3461983/evt-tickcount-not-found-with-python2-6-on-osx-10-6-3,
I saw that suggestion when I read the thread yesterday. If you're willing to give up the 64-bit version, this thread might also be useful: http://stackoverflow.com/questions/7472301/how-to-force-py2app-to-run-app-in-32-bit-mode
This fix doesn't solve the problem of the py2app created relax app not using the bundled Python version and internal Python modules, so some users will still be affected by that.
Yesterday when I was looking at this, I added a 'print sys.executable' to __boot__.py and got: 4/4/12 12:40:10.353 PM [0x0-0x18ac8ab].com.nmr-relax.relax: /nfs/programs/i386-mac/relax/1.3.14/relax.app/Contents/MacOS/python And it doesn't change regardless of what PythonExecutable or PyRunTimeLocation is set to in the Info.plist. So it appears that it is calling the correct binary, but the Contents/MacOS/python is just a binary wrapper for some other python? I suppose I should read the py2app docs at some point. -ben -- | Ben Eisenbraun | SBGrid Consortium | http://sbgrid.org | | Harvard Medical School | http://hms.harvard.edu |
