Mercurial 5.0 rc + Python 3.7 + Apache 2.4.39

[Pierre-Yves David]

Mercurial does not have official python 3 support yet. (version 5.0 is 
the first one with "beta" support).

If you are trying to setup this for production use python 2.7.

If you are indeed trying to test the python3 beta, please file bug at 
https://bz.mercurial-scm.org/

Thanks!
