[Pythonmac-SIG] library locations?

[Dameron Midgette]

Hello all!
    A very newbie question or two. I'm clear that a module needs to be in
macPython's path(s) to be useable, but how about shared libraries? (extension
icon) Do they need to all be in the Mac:Plug-ins folder to work? And what if
there are different file dates for different copies of the same library? 

Mac:Plug-ins:_tkinter
vs.
Extensions:Imaging:PIL:_tkinter (newer)

and

Extensions:Imaging:PIL:_imaging (newer)
vs.
Extensions:Imaging:_imaging

And..what does the OSAm library (Mac:Contrib:OSAm) add to OSA scripting?

                                            Many thanks,
                                            
                                            Dameron
