Returning to the libltdl question: I think we may have a problem here. If we remove libltdl and default to disable-dlopen, then the user will - without warning - slurp all components that are able to build into libompi. This includes everything they specified, BUT because of our "build if you can" policy, it also includes a lot of stuff that they didn't specify and may not even realize is present.
As a result, they not only will have a bloated memory footprint, but they also may very well have slurped in GPL libraries (e.g., if Slurm is present) that could potentially impact their legal situation. We may need to reconsider our build policy in light of this situation.
