test libreant execution

[ael-code]

I've search a little bit, but I did not found a way to test libreant command execution.

Consider this scenario:

pip install --force  gevent=1.0
python setup.py develop
libreant -d

This should fail on python 2.7.8 because of gevent/gevent#513

How do we make travis tests this case scenario?

I was thinking about it, too. I don't have the right solution, but the
quick&dirty one involves shell scripting and adhoc things. If the number
of tests of this kind that we want to do is small, this can be fine, but
it just will not scale.
I think that the very nature of the test you are proposing (incorrect
installation) can't really be tested from python itself (excluding dirty
hacks which would be even more complicated)
