Thanks for the feedback. The build is picking up the python-six and django dependencies.
Package: python-model-mommy Depends: python-django, python-six, python:any (<< 2.8), python:any (>= 2.7.5-5~) Package: python3-model-mommy Depends: python3-django, python3-six, python3:any (>= 3.3.2-2~) I don't think python-six is a Build-Dependency because the code isn't run during build process. The library has a test suite, but it isn't included in the pypi tarball. I've filed a pull request asking upstream to include it. https://github.com/vandersonmota/model_mommy/pull/277 If the test suite was run during the build then python-six and django would be build dependencies. I've added "Team upload" to the changelog. I'm going to rebuild the package and upload a fresh copy to mentors. -- Edward.
