Doesn't setting PYTHONPATH globally mean that *all* python interps will 
see it (including fink's pythonx.y and also python!x.y) and also see it 
with higher precedence than any fink-python-specific one as well?

Doing it as a Runtimevars also means you presume no other package would 
also want to place python modules at some nondefault location (because 
it *sets* the variable rather than prepending to it). That seems like 
the logical approach that a "simple python program that has some 
private-use modules" package maintainer would take who doesn't feel 
like writing a wrapper or writing a -pyXX module. For example 
installing pil-systempythonXX breaks gildas (a good example, along with 
root5, of the safe way to alter a public-use env var).
