I just tried one of them, iconv. First it wants a recent cabal; that's
fine, I installed the darcs version. Then I get this:

Okay, it obviously tries to be smart, but doesn't know that I upgraded
to a separate ByteString library. So I take out the gunk about
'flag(bytestring-in-base)' and try again:
| Setup: At least the following dependencies are missing:
| base <2.0||>=2.2
Of course that was to be expected, since I have base-2.0 hacked to not
get in conflict with bytestring-0.9, and you (Duncan) couldn't possibly
anticipate this (or could you?). Now what am I supposed to do? Give my
messed up base a new version number? (Which one?) Rewrite every single
cabal file, hoping that they never become Turing complete turning the
exercise into a reverse engineering fest rivaling the ICFP contest?
Bite the bullet and install GHC from darcs?
For the time being, I'll go with 'ghc --make'. And I think that cabal
configurations are an exceptionally bad idea carried to perfection.
They make things worse, not better. (And that's just GHC 6.6... I don't
want to even think about what happens on Hugs, JHC and YHC.)
What would it take to talk you into giving up on supporting the broken
base-2.0 and incorporating a patch to unbreak it into the bytestring
setup? Can I stop the insanity by simply writing that patch?

Okay, so now we have *three* almost-stable versions of GHC in wide
circulation, all of them broken in different ways with respect to cabal
packages. I feel tears welling up...
