Thanks for pointing this out, in fact the configure script needs
fixing on Linux as well, it checks for "python" not "python3" (AFAICT
I'm crap at autofools).  Explains why HTML fails to build here because
there is no "python" command anymore so the configure fails even
though "python3" is available and "rst2html" specifies
#!/usr/bin/python3.  It also does some weirdness using "py" for the
python command on windows which according to the Python docs should
find the latest version installed or the version in the script, ie
what rst2html explicitly specifies, even if its in Unix form
/usr/bin/python3.

Cheers
