It seems from the Python documentation that the Mac version of
Python does not include any os.putenv() function which in turn
means that environment variables cannot be changed via
os.environment. I don't really know anything about Mac, but
it might be possible to do something like in the attached
patch. Could you please try it and see if it helps. In that
case we could include it in the future Lilypond versions.
