Created attachment 499852 [details] cabal-1.24.1 build log Build of cabal fails due to an unfullfilled dependency against process (see attached build log). GHC version is 8.2.1.
I can confirm this. $ ghc-pkg list tells me that process is installed in version 1.6.1.0 but cabal requires a version between 1.1.0.1 and 1.5.
