, by a "cabal install cabal-install".
Didn't help much, still stuck. Any hints?
I find that library issues like this with cabal are the biggest time-soak I=
have with using Haskell, and I usually have to abandon attempts to try som=
e new library for various examples.
"Ghc-pkg check" lists lots of warnings, but all from haddock-html or haddoc=
k-interface; not sure what to make of that but I think it just means that s=
omehow documentation was not installed for these packages.
>>cabal -V
cabal-install version 0.14.0
using version 1.14.0 of the Cabal library
GHCi version 7.4.1
HaskellPlatform-2012.2.0.0
