I created a bdist_wininst installer for distutils2 and installed it into my Python 2.7.2 installation. This is on Wondows, 32-bit. I then tried to do a simple install to test it was working.

>python -m distutils2.run install stemming

The initial errors look like complaints about existing packages I have installed by other means (setuptools or bdist_wininst). The final one looks like a bug in distutils2, though.
