Debian with Python 2.6. Setuptools 0.6c9 is installed in site-packages. I'm running a package's setup.py file that begins with the following:
import distribute_setup distribute_setup.use_setuptools() }}}
The use_setuptools() function detects that setuptools is installed and attempts to patch it. This is not a nice thing for use_setuptools() to do, since the user is not trying to install distribute, they are just trying to install some other package that happens to make use of distribute for installation purposes. It especially should not be necessary for non-root activities such as "python setup.py test".
