This doesn't surprise me, naming the binary "python2" is an artifact of
installing two copies of python on the same system because of lack of
backwards compatibility. For the same reason, most distributions have
not yet switched the default "python" to be python3, because it breaks
too many things!

Ideally waf needs to be fixed upstream to work with python3, failing
that then configure needs to try various names for the python
interpreter to find the correct one on the build system - that is what
the configure script is for!

Has anyone tried building without an installed copy of python to see
whether there is a sane error message? Fairly rare, but I suspect there
won't be!
