You might consider using the dirtbike package to turn Python packages from the
Ubuntu archive into wheels (i.e. "rewheel"). Then you could install the
wheels from the archive and the normal packages otherwise.

We use dirtbike (albeit sparingly) in order to support Built-Using
dependencies for pip and friends, so I know it works fairly well, at least for
the relatively simple pure-Python packages that pip depends on.
