[Pythonmac-SIG] ext build problem

All,
Once again I've run into the "_environ" problem while trying to build
4Suite. I'm using python2.3.2 built as a framework build. As part of
trying to debug this, I've written a very simple test that shows the
same behavior for me. I'd appreciate it if someone else could try this
and see if they see the same behavior. Also, if I'm doing something
dumb please let me know. ;)
I will attach the setup.py file and the other files necessary to try
this test. I sure would appreciate any help with this. I've been
banging my head against this for a while and getting nowhere.
thx,
---keith
