Yeah, I talked to the Regina maintainer about this.  He's happier
leaving the libs in /usr/lib rather than using rpath so I guess
he'd feel the same about modifying ld.so.conf.

I've set up the sub-directory for external functions/modules
anyhow so I thought I'd investigate this a bit.

That's why my initial follow-up on rpath.  I haven't found
anything specific in the archives about why rpath would be a
problem in this case; just that many have the impression that
it can cause problems and should be avoided.  I still have the
discussion about plugins in -policy to catch up on though.
