A quick and dirty way to check if another distribution is installed, and to error if it is. This works well at the top of a setup.py file.

Replace 'ConflictingDistribution' with your own conflicting distribution.

You can also only error on certain versions of the conflicting distrubtion by requiring those: require('ConflictingDistribution<1.0'). Of course you'll probably want a better error message then :).
