That sounds good; I'm glad there are a variety of tools out there.

However, this now brings me back to my origional problem. I was
successful at compiling openmpi after disabling vt, but if I want to
use (some of) these tools, I'll need that enabled...So how do I fix
the actual problem and compile openmpi with vt?

Also, as a side note, the rpm generation process also mentioned
several files that were "installed but unpackaged"; many of these look
like they should not be:

warning: Installed (but unpackaged) file(s) found:
