I recently built a binary installer for GHC 7.6.3 to run on CentOS 5.9,
which should be compatible with RHEL 5. It uses glibc 2.5, at least. I
don't have a good place to host it long-term, but would be happy to make it
available to you (or anyone else who's interested).

Hi,
Last summer, as part of the Summer of Code, David Lazar formalized a
significant portion of Haskell 98 in the K framework. You can find the
code here:
https://github.com/davidlazar/haskell-semantics
And there's a talk about it here:
of potential projects, many of which are more widely useful than
Language.C work. This may mean that it would have a relatively low chance of
being accepted. A high-quality proposal would help the odds, however. :)
