And I have looked at the FAQs and help > given at matplotlib's homepage. you can either find and install the *dev packages individually, or do something like this: sudo apt-get build-dep python-matplotlib sudo apt-get remove python Now untar your numpy, go in, build and install: setup.py build sudo setup.py install And last, do the same for matplotlib, preferably with a checkout from svn. Some bugs have been fixed since the last release. Before all of this, you might do well to uninstall whatever versions or parts of numpy and matplotlib had been installed via your previous efforts. The point of the first apt-get is to install things like freetype and the gui toolkits. The only problem is that this also installs an old version of numpy, hence the second apt-get command. The good news is that once you get over the hump of having the dependencies installed, subsequent updates and compilations of numpy and matplotlib are easy. It is usually advisable to delete the build directory, since setup.py is not very smart with respect to knowing what needs to be recompiled. Sometimes it is also necessary to clean out the old version from its installation location. See attached script for an example of mpl uninstallation.
