That would certainly be possible.

It's rather easy to find the right Makefile: just look
for os.py (the landmark used in Python to initialize sys.path
on startup), join it's path with "config" and you're there.

More details can be found in Modules/getpath.c of the Python
source distribution.

You can then have distutils parse that file to extract
the other details.

Note that this doesn't work if you're importing from a
ZIP file.
