Yeah, that's not a particularly good idea. I suppose it would work for those who generate the makefile and use it themselves on the same workstation. For makefiles that are included in source tarballs it would only make the problem worse. > I have two possible fixes: > > The first would be to decouple the commands from the libraries.

If this approach is chosen, will the commands still invoke the Python 2 version if only that one is installed? > The second option would be to retain the multiple versions, but to > manage the links with alternatives so the unversioned commands will > default to whatever version is installed and again, Python 3 would be > preferred if both were installed. This approach seems like it would work for my use case. Ahven uses Sphinx to generate its documentation, using Sphinx's generated makefile that invokes sphinx-build. I have ahven.spec regenerate the documentation, but the makefile is generated upstream. Until the Ada domain gets ported, the Ahven build will have to use the Python 2 Sphinx, but I'd rather not encode that in ahven.spec. I want to keep that dependency contained in python-sphinxcontrib-adadomain. Ahven shouldn't need to even know that Sphinx is written in Python. If I can have python-sphinxcontrib-adadomain depend on the Python 2 Sphinx specifically, and then have the ahven package require python-sphinxcontrib-adadomain, plus python-sphinx or python-sphinx-bin or whatever but not python2-sphinx, and invoke sphinx-build and know that it will run on Python 2, then I'm satisfied.
