380	Ability to blacklist packages that are on hackage	guest		"Sometimes there are packages on hackage that I don't want to install, perhaps ever.  Maybe there is a buggy release I'm trying to avoid, or something of that nature.

So, my proposal is a user defined blacklist.  I think the version specification could work just like that of a .cabal file.

I also think cabal should tell you when it skips a dependency due to blacklisting."	enhancement	new	normal	cabal-install-0.14.2	cabal-install tool	1.2.3.0	normal				hard (< 1 day)	6.8.3
