Hmmm... yes, this is a reasonable idea. The BuildPreReq we definitely
cannot change because Expect requires definitely _both_ the sources and
the installed files and if they do not match it too easily can break
under build-time. But relaxing the PreReq is a very good idea because
a break under run-time is less likely and it would be broken usually
during updates only. I've relaxed the dependency now as you suggested:

Thanks for the idea.
