Can't get tkinter installed since it conflicts with wxpython (see below)
in 2.5, which seems to be default (and doesn't react to -wxpython). So
py25-matplotlib isn't installed with tkinter.

Anyway, using show() and backend : TkAgg on either python 2.4 or 2.5
pops up a blank X window and then segfaults python. Here's what I have
installed:

$ port installed | grep matplotlib
  py-matplotlib @0.90.1_0+numpy+tkinter
  py-matplotlib @0.91.2_0+tkinter (active)
  py25-matplotlib @0.90.1_1+gtk2+numpy
  py25-matplotlib @0.90.1_1+numpy+tkinter
  py25-matplotlib @0.90.1_1+numpy+wxpython
  py25-matplotlib @0.91.2_0+cairo+wxpython (active)

Also I get a pile of 

Break on
__THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION
_FUNCTIONALITY___YOU_MUST_EXEC__()
to debug.
The process has forked and you cannot use this CoreFoundation functionality
safely. You MUST exec().

during compiles.
