Summary: Explicit interp reference during build fails
Initial Comment:
I think this is MacPython-specific and not just a general
Python build issue. If I explicitly reference the Python
executable when building an out-of-tree extension module I
get an error building the .so file because it stripped the
dirname() of the python.exe file.
Here's a simple example. I have a directory with a single
extension module and simple setup.py. I want to build it
with
~/src/python/head/dist/src/build.pg/python.exe
Compilation works fine. Linkage bombs.

Skip,
I think this problem has gone away as a side-effect of the new way to
create extension modules, at least if you make sure you have
MACOSX_TARGET_PLATFORM=10.3 in your environment when configuring
and building python.
Could you try, please, and close the report if this appears to work for
you? Otherwise please reassign back to me.

This won't be fixed for 2.3, after discussion on python-dev it
seems the situation is not so common, so it can wait for 2.3.1.
