→ guix import hackage parallel-io Syntax error: unexpected token : (buildable (False)) (at line 52, column 8) Syntax error: unexpected end of input guix import: error: failed to download cabal file for package 'parallel-io' I had a quick look at the importer, but a solution didn't immediately present itself, so I'm filing a bug instead. I came across this when attempting to package sizes, also from hackage. Thanks, Chris
