Hi Darren,
I think your correct, the matplotlibrc file says that the backend is set to
Agg.
Here's the traceback:
BUILDING MATPLOTLIB
matplotlib: 1.1.0
python: 3.1.2 (r312:79147, Sep 27 2010, 09:45:41) [GCC
4.4.3]
platform: linux2
REQUIRED DEPENDENCIES
numpy: 1.6.0
freetype2: 9.22.3
OPTIONAL BACKEND DEPENDENCIES
libpng: 1.4.7
Tkinter: no
* Using default library and include directories for
* Tcl and Tk because a Tk window failed to open.
* You may need to define DISPLAY for Tk to work so
* that setup can determine where your libraries are
* located. Tkinter present, but header files are not
* found. You may need to install development
* packages.
Gtk+: no
* Building for Gtk+ requires pygtk; you must be able
* to "import gtk" in your build/install environment
Mac OS X native: no
Qt: no
Qt4: no
Cairo: no
OPTIONAL DATE/TIMEZONE DEPENDENCIES
datetime: present, version unknown
dateutil: 1.5

OPTIONAL USETEX DEPENDENCIES
