Probably. If the libraries cannot be located by the system in a
standard path, it needs help. We could probably come up with a small
script which prints the needed settings for a local M3 workspace.

Have you got a better suggestion?
This is really not an M3 problem, but a general Unix question.
How should dynamic shared object files be found (especially, when
they are scattered across an M3 workspace)? If we burn in the local
paths, we need to relink the objects before shipping. I also wouldn't
like it when some installed program stops to work because the original
creator made changes to his home directories...

Any ideas?
