haskell importer problems?

[ng0]

I'm manually constructing those packages as the importer fails. As not
only `guix import hackage graphviz' fails but also `guix import hackage
darcs', I assume it is not due to names..

address@hidden ~/src/guix/guix-darcs$ guix import hackage graphviz
Syntax error: unexpected token : { (at line 6, column -1)
Syntax error: unexpected end of input
guix import: error: failed to download cabal file for package 'graphviz'

address@hidden ~/src/guix/guix-darcs$ guix import hackage darcs
Syntax error: unexpected token : (buildable (False)) (at line 513, column 4)
Syntax error: unexpected end of input
guix import: error: failed to download cabal file for package 'darcs'

Anyone got a solution for this?
