[Pythonmac-SIG] problem compiling extension modules for 10.5

[Garry Willgoose]

I have posted this problem a few months ago on several places but it  
has languished.

I have been developing an extension using ActivePython 2.5.2 under  
10.4 for some time now. When I switched to 10.5 I can no longer do  
this. The module compiles fine but when I import the library I get the  
following message ...

willgoose-macpro:modules garrywillgoose$ python
ActivePython 2.5.2.2 (ActiveState Software Inc.) based on
Python 2.5.2 (r252:60911, Mar 27 2008, 17:40:23)
[GCC 4.0.1 (Apple Computer, Inc. build 5250)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
 >>> import tsim
Fatal Python error: Interpreter not initialized (version mismatch?)
Abort trap

Now when the module is compiled on an old 10.4 machine (same python,  
everything) and then copied to the new 10.5 machine it works fine. The  
error I believe from what little I have already found out is because  
the versions (compilers, libraries, etc??) of python and my module are  
incompatible (somewhere I saw that activepython is compiled against  
10.4). I tried setting the environment variable

MACOSX_DEPLOYMENT_TARGET=10.4

but still no go. Any suggestions.
