libmpfr-dev needs to be installed on your main OS; GUB will not
build that itself.  I think you already knew that, but I'm adding
that advice here in case somebody else tries to solve this and
runs into the problem.

That dependency is noted in the README, but it's not particularly
easy to find.

I have a vague recollection of trying a 32-bit build and not
seeing any difference, but I wouldn't swear to it.  As for Jan,
how long as did you ask him?  I don't think that we can / should
rely on responses from any one particular person, especially if
it's been more than a few weeks.

It would be great if other people tried out GUB themselves --
maybe a it'll work just fine on Redhat (which could help debug the
problem we see on ubuntu), or maybe it won't but a fresh pair of
eyes could see something that was missed.

There's no connection between that and 1993, 1943, or 1948.
