pymutester fails on missing parentheses in exec
I just installed pymutester with pip3 install pymutester. This worked (seemingly), but gave an error:
$ pip3 install pymutester

Cleaning up...
When I try to execute mutant-nosetests, I get the same error.
Perhaps pymutester doesn't support Python 3?
tests fail: "AssertionError: Test output is different"
I just tried to run pymutester's own unit tests. Not good:
$ nosetests
