[Haskell-cafe] can't build testpack

[Krzysztof Skrzętnicki]

testpack builds fine for me. In the original .cabal file there are following
lines:

>>>
 If flag(splitBase)
   Build-Depends: base >= 3, containers, random
 Else
   Build-Depends: base < 3
<<<

Now that I think about it you didn't actually said what is your GHC version.
Knowing that you can replace lines above with one line that matches your
specific configuration.

GHC 6.8.3 :
   Build-Depends: base >= 4, containers, random
GHC 6.10.1 :
   Build-Depends: base >= 3, containers, random

Please take care to restore and modify the original file.

I think you should read Cabal user guide. This will save your time in the
future:
http://www.haskell.org/ghc/docs/latest/html/Cabal/index.html

I *hope* those changes will fix your installation. I can't really test it,
because testpack build fine with my version of cabal:

Perhaps it may also be the difference of installing with "cabal install" and
"runhaskell Setup build".
