I’ve been struggled during some time today on how to get running PyRoot in Snow Leopard. I was getting the following error:
[pb-d-128-141-141-210.cern.ch]:~% python
Python 2.5.4 (r254:67917, Dec 23 2008, 14:57:27)
[GCC 4.0.1 (Apple Computer, Inc. build 5363)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import ROOT
Fatal Python error: Interpreter not initialized (version mismatch?)
zsh: abort python
the problem is likely solved in the second situation b/c the locations given for the libraries of python don’t match those of the binary. In any case, it’s not necessary to set (DY)LD_LIBRARY_PATH for python, as the binary knows how to locate its library (it’s a different matter when using TPython from CINT, as CINT needs to locate the python library).
But check which python and see whether it matches the system one?
thanks for your explanation, although I am not sure to understand…

In my path I made sure /usr/local/bin comes first than /usr/bin, the latter being where the different apple built-in python binaries are installed, the rest of the stuff being located in /System/…:

On the other hand,if I do not explicitely specify DYLD_LIBRARY_PATH I got the first error posted in this thread.
sorry, I missed that you were using a local version of python. Having a look at the structure, I note that there is no libpython2.5.* in (the equivalent of your) $PYTHONDIR/lib to link with. In my case, that library is in /usr/lib, and would in /usr/local/lib for you. Do you have that path in (DY)LD_LIBRARY_PATH?
