matplotlib-devel Mailing List for matplotlib

I built matplotlib on linux from source using:
python setup.py build
python setup.py install --home=3D/home/tom
when I try to import=20
>>> import pylab
Traceback (most recent call last):
 File "<stdin>", line 1, in ?
 File "/home/tom/lib/python/pylab.py", line 1, in ?
 from matplotlib.pylab import *

ImportError: No module named _nc_backend_gdk
When I look in the backends dir in
/home/tom/lib/python/matplotlib/backends i see the following files
which does not include the .so file for _nc_backend_gdk
__init__.py backend_gdk.py backend_qtagg.py
__init__.pyc backend_gdk.pyc backend_qtagg.pyc
_na_backend_agg.so backend_gtk.py backend_svg.py

Is there something I am doing wrong?
