   instead, LIBEXECDIR would be set at runtime, relative to the emacs
   invoked binary.

Won't work, where do I find libexec if I put my emacs binary in ~/?
Where is libexec relative to that? What about where all the shared
data is?

(emacs does support setting a different version of movemail using the
rmail-movemail-program variable, but we are talking about totally
dynamic look up here so that isn't relevant)
