Hello,
It seems to me that the "build depends" attribute/field is only informational, i.e. it doesn't cause "faulting in" dependencies if not present? If true, this seems to be a deficiency in cabal. ??
Kind regards, Vasili
PS It seems to me that for HaskellDB the "build depends" is incomplete in that it should contain "old time" and "TextPrettyPrint.HughesPJ"??
