This was mentioned on the mailing list (see http://lists.idyll.org/pipermail/testing-in-python/2011-June/004173.html).

Here is an example tox session

Notice how even though installing the dependency fails, it runs without any problems the second time around. This happens when there is any kind of error installing a dependency, not just downloading.

this issue should be fixed - you can test with the release candidate:

pip install -i http://pypi.testrun.org -U tox
