I've installed matplotlib for Python 3.2 before, but now I can't do it in my new computer, and I'm banging my heads.

I've tried a bunch of instructions on the web, and none have worked for 2 of my computers. It just wouldn't really install.

Python 3.2.3 (default, Oct 19 2012, 20:10:41)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import matplotlib
Traceback (most recent call last):

Any idea what went wrong?
