[Pythonmac-SIG] Python 2.3.4 Installation

[tmk]

Hi Bob,

First I must confess that I don't really understand the details of the  
problem of building extensions with multiple versions of Python  
installed on Panther...

Out of curiosity I just checked and the lib/python2.3/config/Makefile  
file from my compiled from source python 2.3.4 don't appear to be  
patched with the patch below.

Am I correct in assuming that this is ok and that the patch below is  
only meant for the Apple-installed python 2.3?

Also in a separate but related e-mail you also suggested that one would  
"also need to set the "MACOSX_DEPLOYMENT_TARGET" environment variable  
to "10.3" when using this patch."

Could you please elaborate on how/where one should set that environment  
variable (I set it in ~/.MacOSX/environment.plist).

TIA for any advice.
