Comment (by eschnett):

 No, the hwloc package manager's decision is not correct. libhwloc-dev
 provides a library libhwloc.a that cannot be used without libltdl.a. Thus,
 it either needs to depend on the libltdl-dev package, or needs to provide
 a library libhwloc.a that does not have this dependency.

 If you want to provide a work-around, then I suggest to do this in the
 system-specific file "ubuntu.cfg" of Simfactory. Of course, you can also
 check in hwloc's configure script whether we are using the system hwloc
 library, whether it depends on libltdl, whether this library is installed,
 etc., and if so, refuse to use the system library. We usually don't go to
 these lengths when looking for existing libraries, though. If you really
 want to go this route, then I would suggest using autoconf or cmake for
 this, which provide exactly this kind of functionality.
