Hmmm, but the config files themselves can be changed to load anything.
Just rename the targets.
The .root parameter points to wherever you want and then you have
something like display/memory.so which may or may not be the actual
But I suppose if the config files were user-read-only/root-write, this
wouldn't be such a problem.

I can't assume where the user is going to install the libraries. The
problem is that I don't want the end user to have to patch binaries in
order to make the libraries work. I can't assume that the person has the
ability to do this without screwing it up.
How about if we #ifdef around that code. Windows will be the only OS
which can use an environment variable. The others would still be hard
Of course, if windows supported links across drives, this wouldn't be a
