Comment(by edsko):

 I got the same problem (ghc-7.4.0.20120119). Worked around it by disabling
 haddock in build.mk. After that it installed, but then when I tried to
 build cabal-install *that* failed with a divide by zero error. After some
 tracking down, turns out things seem to be very broken:

 # ghci
