Using 'python' binary for Python 2

[zatherz]

PEP 394 recommends the usage of python2 when invoking Python 2 scripts instead of python, as the latter might be different depending on the distribution (and indeed it is - it's Python 3 in Arch Linux).

Which script(s) are you talking about?

Upon further inspection, it seems that it's actually cmake generating it like that.

The script comes from fcd/python/bindings.py (but doesn't have a shebang). It might not be a ton of effort to make it 2-3 compatible. Would you like to do it?

With that said, fcd itself is likely to keep linking against Python 2 for a while.
