My extremely similar tool: dynpk (Score 2, Interesting)

I very recently published a tool that performs a similar task. dynpk (my tool) bundles programs up with packages from your system, then wraps them with some other stuff to create a bundle that essentially allows you to run a Fedora program on a RHEL machine (and probably Ubuntu or Debian, but this is outside my needs...).

Recompiling loads of libs for RHEL isn't fun or particularly maintainable. Therefore, use the ones from Fedora!
