I believe the motivation for this was simply to reduce the depth of 
tracebacks; consider an administrator who doesn't know much about Python 
and is trying to install a package.  If they get a big long traceback 
from deep inside the guts of Distutils, they may think the package or 
the Python installation is broken because they don't read all the way 
down to the bottom and see that it's a permission problem.

I suggest just documenting the DISTUTILS_DEBUG variable, but otherwise 
leaving this alone.
