Well, that's doing the right thing. My guess is that it's some minor
error somewhere in your build system or something. It sounds like one
of those things that'll be very difficult to debug via email this way.

Here's one place to start, though. Forget GRC for the time being and
just make sure that you are installing your component correctly. So
first build and install your component, Umbrella. Then simply pop open
a Python interpreter ('python' or 'ipython' if you have the latter
installed):

import Umbrella
dir(Umbrella)

The output of the dir() command should show you what blocks are
actually installed as part of this component. That'll give you a clue
how your installation process is working.
