[Bf-committers] Python 1.5 is wrong, 2.2 works, probably 2.0 a must

[Guillermo S. Romero / Familia Romero]

Hi:

More light in the Python thing.

$ python1.5
Python 1.5.2 (#1, Apr  3 2002, 18:16:26)  [GCC 2.96 20000731 (Red Hat Linux 7.2 2 on linux-i386

$ python2.2
Python 2.2 (#1, Apr 12 2002, 15:29:57)

Clearly, 1.5 is not enough.

That should fix it. Everyone running .2 of the 2 series, right? If
someone is sure it works with 2.1 or 2.0, change the line in the
patch, to avoid requiring the latest just for fun.

And to the problem I had about python2.22.2 or similar, it is due this

PYTHON has the exec name that is working and is going to be used, or
should, PYTHON_VERSION will just cause havoc in a system with multiple
pythons installed. Or at least does in the one I tested. :]
