Matplotlib plots not showing up in Mac OSX?

Question

I am running Mac OSX 10.5.8. I installed matplotlib using macports. I get some examples from the matplotlib gallery like this one, without modification:

I only had python 2.5 and I did not want to install python 2.6 on my mac. So I used different procedure mentioned in the following link to solve this problem:

What that one actually needs is the following steps:

1) Searching where is the directory "pygtk-2.0.pc" and locate it. For example mine was located in the following directory:

/opt/local/lib/pkgconfig

2) Adding the path information to envirement variable. For example:

PKG_CONFIG_PATH=/opt/local/lib/pkgconfig
export PKG_CONFIG_PATH

3) Download the configuration information file "matplotlibrc" from matplotlib website http://matplotlib.sourceforge.net/_static/matplotlibrc

4) Change backend to MacOSX in the file and save it

5) Copy the file to directory .matplotlib You can locate the directory in python by the following command:

import matplotlib
matplotlib.get_configdir()
