That's because by default, python does not look into
$HOME/src/numpy/.... You have several ways of controlling that, but
the easy one is PYTHONPATH. This environment variable should contain
your site-package, which is the $prefix/lib/python2.4/site-packages
here where $prefix is what you gave to --prefix.
PYTHONPATH is only on of the way to modify sys.path, which is what is
used by python in the end:
# python will only look for packages which are sys.path
python -c "import sys; print sys.path"
You can check the path of the package after import:
python -c "import numpy; print numpy.__file__"
