If you install shared libraries into a directory which is not looked in by default by ld, you should add it to the LD_LIBRARY_PATH, e.g.:

LD_LIBRARY_PATH=$HOME/local/lib:$LD_LIBRARY_PATH python -c "import numpy"

Ok, that makes sense to me.  I tried to see what the current value is by doing        echo $LD_LIBRARY_PATH

It is very possible that you don't have it defined by default on your platform. The undefined variable may be a peculiarity of the cshell - the instructions I gave you assumed a bourne shell or compatible.

David

Ok, I assumed as much and proceeded by simply setting the environment variable.  I did not add the part where you said        python -c "import numpy"

What does that part do?  It turns out that by fixing my library path, numpy now imports.  I assume that my installation of h5py doesn't need to be redone just because I reinstalled Numpy?

Try: $ python
