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.
This is an issue with tcl, you need to configure tcl with --disable-corefoundation - I've informed tcl's maintainer
$ sudo port -d upgrade py25-matplotlib +cairo +tkinter -wxpython
tkinter is a default variant so you don't need to specify +tkinter, also wxpython is disabled by default so again you don't need to specify -wxpython. If you want to build with wxpython support you'll need to build with [ram@skymoo ~]$ sudo port install py25-matplotlib -tkinter +wxpython

I notice you're trying to upgrade the port, AFAIK you cannot specify new variants on upgrading a port; if you want to modify the variants used you'll need to reinstall. I I don't get this error when trying to install the port using the above variants [ram@skymoo ~]$ sudo port install py25-matplotlib +cairo +tkinter -wxpython ---> Fetching py25-matplotlib ---> Verifying checksum(s) for py25-matplotlib ---> Extracting py25-matplotlib ---> Applying patches to py25-matplotlib ---> Configuring py25-matplotlib ---> Building py25-matplotlib with target build ---> Staging py25-matplotlib into destroot ---> Installing py25-matplotlib 0.91.2_0+cairo+tkinter ---> Activating py25-matplotlib 0.91.2_0+cairo+tkinter ---> Cleaning py25-matplotlib [ram@skymoo ~]$ python Python 2.5.1 (r251:54863, Dec 13 2007, 12:28:27) [GCC 4.0.1 (Apple Inc. build 5465)] on darwin Type "help", "copyright", "credits" or "license" for more information.

I'm not sure what to suggest as I cannot reproduce the errors you've encountered... Cheers Adam
