looks like there is a bug about this:
https://github.com/haskell/cabal/issues/1137

seems you need to reinstall cabal or something like that.

One more thing... For my HTTP needs I've been using without problems Network.HTTP.Conduit:
http://hackage.haskell.org/packages/archive/http-conduit/1.2.1/doc/html/Network-HTTP-Conduit.html

but I didn't research in which ways these two packages differ.

Hello,

 which is your GHC version? On the page for that package it is written that it was successfully built for GHC-7.6. Maybe your GHC version is too old? Otherwise I don't have a clue.
