Clearly, the upstream should be runnable on any combination of
anything, for the purpose of developer setup games, but once you
start building packages for particular distribution, be it RHEL
or Fedora, those packages should have a clear dependency on other
things in that OS distribution.

The best solution seems to be to

	s%^#!/usr/bin/env\s(\S+)%#!/usr/bin/$1%

in rpm build time so that in rpm-based installations, you know what
ruby / python / whatever you are using and there are no nasty
surprises.
