[Pythonmac-SIG] Interpreter not initialized

[Scott Frankel]

I'm not sure I can upgrade to python26.  Meanwhile, if I understand  
your otool suggestion correctly, I've gotten seemingly ambiguous  
results.  (See below.)

Macports has installed the pyqt libs deep in its directory structure.   
Pointing otool to QtCore.so, for example, returned a Python that's  
neither /System nor the Macports deep installation.

Am I using otool incorrectly?  Or interpreting the results incorrectly?

Thanks again!
Scott




% otool -L /opt/local/var/macports/software/py25-pyqt4/4.4.4_0/opt/ 
local/lib/python2.5/site-packages/PyQt4/QtCore.so
/opt/local/var/macports/software/py25-pyqt4/4.4.4_0/opt/local/lib/ 
python2.5/site-packages/PyQt4/QtCore.so:
	/opt/local/Library/Frameworks/Python.framework/Versions/2.5/Python  
(compatibility version 2.5.0, current version 2.5.0)
	/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current  
version 7.4.0)
	/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current  
version 1.0.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current  
version 111.1.1)
