The python scripts must be invoked with $(PYTHON) as done
throughout the build system.

SeaBIOS uses:
$ rgrep -i python tools/firmware/seabios-dir
tools/firmware/seabios-dir/tools/transdump.py:#!/usr/bin/env python
tools/firmware/seabios-dir/tools/buildrom.py:#!/usr/bin/env python

tools/firmware/seabios-dir/tools/readserial.py:Or: apt-get install python-serial
tools/firmware/seabios-dir/tools/checksum.py:#!/usr/bin/env python

Does this not work? Should python be on your $PATH?

It is. But the python binary on NetBSD's pkgsrc
is called python<version>  to allow concurrent installations of different
python versions.
So I can have: python2.5, python2.6, python2.7, python3.1, etc.

There is no current "python" referring to the default version?

I think this is something you will need to work out with the SeaBIOS
upstream.

Since SeaBIOS is third party code we are not so much at liberty to make
the same sorts of policy decisions as we would for our own code.

You could perhaps attempt to work around this by invoking the recursive
make into the seabios directory with PATH=$(dir-only $(PYTHON):$PATH or
whatever the appropriate runes are.

Or you could try posting a patch to SeaBIOS-devel, I don't know what
their thinking on this sort of thing is.

I see.

What python version does SeaBIOS require?
I have python 2.5 installed.

I manually created a python symlink to that version and then I get this failure:
