Fink should probably test positive with sys.prefix.startswith('/sw')

However... testing for Fink vs. MacPython is the Wrong Thing To Do.  
You should just try and detect TclTkAqua versus X11 TclTkAqua, not Fink 
vs MacPython.  It's possible to use TclTkAqua with a Fink Python or X11 
Tk with MacPython.  I'm not familiar enough with Tcl/Tk to know how, 
though.
