The user is trying to do that. No, that should work fine. I don't know how the egg-based matplotlib/pylab should work with the installed-from-source numpy, though. If the versions are compatible, then I expect it would work. You gave a traceback resulting from "from pylab import *" after installing the two eggs, correct? If so, what was the result after you installed numpy from source? I would expect no difference, because the problem reported in the traceback is a missing matplotlib module, not a missing numpy module. Or did you mean that you installed matplotlib from source? That would make more sense, and certainly should work if all the right header files and libraries are present. If you installed matplotlib from source, what do you get from ls /usr/lib/python2.4/site-packages/matplotlib/backends/*.so Another diagnostic would be to delete the build directory from the matplotlib source tree (assuming you are now building matplotlib from source), and save the output from the "python setup.py build" command. This should make it clear whether the necessary headers really were found.
