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. ??
I'm not quite sure what you mean. They are certainly not just informational. If you miss dependencies then the package will not compile. If by "faulting in" you mean downloading and installing missing dependencies, then that's exactly what the cabal-install tool does. As you mention in your other email, Cabal and cabal-install do indeed access the db of installed packages and build a dependency graph. cabal-install also uses a simple constraint solver to find a satisfactory dep graph of installable packages.
