Great!

Ehhh? I found it? But the evil part of me has attached the tar ball.

As Mike already pointed out you have to hack some local gschemrc to
set up component libraries et al. When gschem starts it looks for rc-files
in three places in the following order (from the top of my head):
1) Current working directory (which is where I have put them)
2) ~/.gEDA/gschemrc
3) .../share/gEDA/system-gschemrc

In my attached example I have both a gschemrc and a gnetlistrc. Both calls
a commonrc which sets up the paths. gnetlistrc also changes the default
behavior for hierchial designs when running gnetlist. OK, it's scheme
code, but it's very simple. Just remember the ()'s ;-)

Note that you have to start gschem from the dirctory you have your project
wide gschemrc.

This really calls for a project manager. That would really overcome this
cumbersome steps. But it's easy once you done it.

Hope it's getting clearer,
