I've recently added a second Python install on my OS X box, in /opt/Python. I've got a script with a shebang at the top:


When I run the script like so:


It runs fine. If I just:


I get an error:

Fatal Python error: Interpreter not initialized (version mismatch?)
Abort trap

and I can confirm that it's running the script in the System python - the first two lines in the script are:

import sys
print sys.path

Which prints:

['/opt/myProj', '/System/Library/Frameworks/Python.framework/Versions/2.3/lib/', '/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3', '/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/plat-darwin', '/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/plat-mac', '/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/plat-mac/lib-scriptpackages', '/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/lib-tk', '/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/lib-dynload', '/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/site-packages']

So why is Mac OS X not using the python spec'd in the shebang?

(I also checked the line endings - unix.)
