                komodo.exe

                Frameworks/
                    Python.framework/... # siloed Python base install dir

                komodo

            Frameworks/
                Python.framework/...     # siloed Python base install dir

    Linux/Solaris dev build:
        $mozSrc/dist/
            bin/
                komodo.exe
                python/         # PyXPCOM site lib (can't use this dir)

                python/         # siloed Python base install dir

    Basically the above makes this config var easy: the siloed Python in
    dev trees is always in $mozSrc/mozilla/dist/python/... except on Mac
    OS X.
    
    Note: It would be nice if this "appropriate" place worked with how
    Firefox is current distributed (e.g. so that a separate PyXPCOM
    Firefox extension and/or Komodo that installs as an add on to a
    xulrunner install or something like that could work.) No guarantees
    this time around.
