python expects to find modules (such as numpy) into a list of
directories, some of which are hardcoded at installation time for
python. You can prepend a directory (or a set of directories) using
the PYTHONPATH environment variable.

For example, installing numpy insto $HOME/local:

python setup.py install --prefix=$HOME/local

numpy will be installed in $HOME/local/lib/python2.5/site-packages
(for python 2.5), and you should set your PYTHONPATH to
$HOME/local/lib/python2.5/site-packages for python to find it:

PYTHONPATH=$HOME/local/lib/python2.5/site-packages:$PYTHONPATH python
-c "import numpy"
