[Haskell-cafe] no end to the build errors! (wxhaskell, afrp)

[Yang]

argh, still more build errors on various fronts. i'm using ghc-6.6 on
fedora core 5 unless otherwise noted. thanks in advance for help on
any of these.

a lot of this is part of my attempt to learn more about and play with
a high-level functional gui library (and, of course, for getting a
better grasp on what frp and arrows are all about) after realizing
that i would never ever be able to get fruit working. i have so far
found wxfruit (built on wxhaskell) and FG (built on gtk). i am
interested in implementing a similarly 'highly-declarative' ui library
built on hscurses.widgets.
