Bug#975560: M-x pyvenv-workon fails with "No such file or directory, python"

[Stefano Zacchiroli <zack@debian.org>]

Package: elpa-pyvenv
Version: 1.21-1
Severity: important

Since the removal of the /usr/bin/python -> python3 symlink, M-x pyvenv-workon
fails with the following error message:

  zsh:1: command not found: python
  apply: Searching for program: No such file or directory, python

Installing python-is-python3 fixes the issue, but is clearly not the right
solution. pyvenv should be able to enter a virtualenv no matter what, given
that is where the "right" python version will be found.

Thanks a lot for maintaining elpa-pyvenv in Debian!
Cheers
