We can also suggest that users use the gentoo-haskell overlay as
suggested in the Wiki, if this would help reduce the release turnaround
time.

In fact, we are currently putting together a new download page. Perhaps
you could read over the Gentoo installation instructions and suggest any
changes you would like to see made.

I can see how this might be the case. Regarding the haskell-platform
ebuild, as far as I can tell there are only lower bounds on the included
libraries. I think it would be wise to at least upper bound the major
version.

Mark, what are your thoughts on this? I have seen a few distributions
providing "Haskell Platform" releases that place rather loose bounds on
the included libraries. It seems this could come back to bite us at some
point.

Great!
