[Haskell-cafe] Cabal install fails due to recent HUnit

[Martijn Schrage]

Hi Erik,

A similar thing happened to me with the GraphViz package. As Duncan 
explained to me, the problem is that Cabal-1.10.0.0 (and I believe also 
1.10.1.0) incorrectly reports an error when conditionals are used in 
test suites.

Upgrading to Cabal-1.10.2.0 (or cabal-install-0.14.0 with Cabal-1.14.0) 
should fix the problem. Unfortunately, this means your build will not 
work on a fresh Haskell Platform v2012.2.0.0, until HUnit is patched in 
the hackage index.

Cheers,
