With a proper debian configuration, this should be as easy as

sudo apt-get install python-matplotlib

If can't do this because your debian distro is too old or because you
are not properly using debian package management, you may consider
getting a newer distro (ubuntu is a debian distro that is current and
popular with scientific python users and developers) and/or spending the
time to get a smoothly functioning apt configuration so you can
upgrade painlessly and w/o fear.
