There's a discrepancy because package management on Python is
completely broken. Distutils and Setuptools (and it's new fork,
Distribute) are inadequate- they act as installers, but don't provide
a way to uninstall the program. There are attempts to fix this, such
as pip and Activestate's PyPM, but they aren't used as widely as the
older methods.
