Which code is "the code"? The code distributed with Python works
fine when installed in /usr/local.

Which modules are you talking about? If you have pure Python
modules you can make them available to Python 2.1 by copying the
source files to /usr/local/lib/python2.1/site-packages and
running compileall.py on them. Extension modules have to be
recomplied for 2.1. Its easy if the extensions use distutils:
$ python2.1 setup.py build
$ su
$ python2.1 setup.py install

Bad idea. The stuff in /usr/lib/python1.5 is for Python 1.5. It
might by chance work with 2.0 or 2.1 but don't count on it.
