Package: cabal-install
Version: 1.24.0.1-3
Severity: important

Dear Maintainer,

Trying to do:

% rm -r -f $HOME/.cabal
% cabal install gitit

results in:

cabal: failed to parse output of 'ghc-pkg dump'

Here are the paths/versions to the programs above:

% which cabal
/usr/bin/cabal
% cabal --version
cabal-install version 1.24.0.1
compiled using version 1.24.1.0 of the Cabal library 
% which ghc-pkg 
/usr/bin/ghc-pkg
% ghc-pkg --version
GHC package manager version 8.0.1

Thank you for your attention,

Stephane Popinet
