How difficult is it just to create an RPM for yourself and then put it
up in some repository for other people to use?

I never use cabal-install to install packages at home (with the
exception of testing versions of libraries I'm writing as I'm writing
them); instead I create a new ebuild for whatever I want and then put
that in the Haskell overlay for Gentoo.
