I've had some trouble with finding libraries too.

It seems they ought to be set in rc, without changing rc.  See the
ldconfig lines there.

You can see what library paths the system knows about with
ldconfig -r.

You can add a path with ldconfig -m /usr/X11R6/include/whatever,
for example.  This merges instead of replaces.
I put this in rc.local:

ldconfig -m /usr/X11R6/lib /usr/local/lib /usr/lib/compat

which is basically what rc is supposed to do but didn't seem to be
doing.  You can add directories.
