That's not really needed if matplotlib stores its datafiles in the same directory as its python files (that is in the package directory). In that case you can just explicitly include matplotlib (using the packages option). If that works you can create a recipe that does the same automaticly when a program depends on matplotlib.

That doesn't sound too good, do you mean the datafiles aren't in the package directory?

What shortcut links? Py2app special-cases the python framework because we know how it is structured and know what parts must be copied into the application to get a working bundle.
The tcl/tk framework is treated specially and that should mean the entire framework is copied verbatim. That again means that it shouldn't be necessary to specify that some additional datafiles in that framework should be copied because they'll be included anyway.
