any program that builds sets of shared libraries with dependencies on
each other seems like it would have similar issues.  you need them to
link with each other from the build locations at compile/link time, but
have an rpath coded into them for the installation location.

passing -ldopt to ocamlmklib omits the generation of rpath, so the
resulting libraries don't have any rpath encoded into them.  the test
would be if oxenstored runs.  (I think it has currently been excised
from the build...)
