The biggest problem with upper bounds (or not), is that frequently,
somebody will update a package that requires a bleeding edge GHC. I, on
the other hand, often need to install software on older systems (last
time was Fedora 17, more than a year old, and shipping GHC 7.0.4).
Needless to say, central packages like template-haskell, array,
stringable, and happy all fail to compile, and then I try to manually
install older and older versions of these packages, until one of them
finally works. This is time consuming and cumbersome, and while I can
do it, I clearly cannot inflict this on my users.
(And some systems I have to work with - typically "enterprise"
distributions - ship with even older GHC versions, but then I typically
compile GHC from source.)

I'd love to, what do I need to do?

This is great, any chance of including yet older compilers? The sad
fact of life is that people use "enterprise" and "LTS" distributions,
which inevitably means outdated software..
If I haven't seen further, it is by standing in the footprints of giants
