Can a Python package depend on a specific version control revision of another Python package?

Question

Some useful Python packages are broken on pypi, and the only acceptable version is a particular revision in a revision control system. Can that be expressed in setup.p

Answer 1

If you really require an obscure version of another package, and there's no way to make do with other versions, you might want to simply distribute that version of the package with your own. If necessary put it in your own namespace to ensure that your version is the one that is used.
