Re: [Haskell-cafe] already installed packages alerted as not being installed

Hello,

thanks I wanted to mention that the "unknown symbol" error is very likely not related to the cab tool as the same error appears, when using the cabal - tool. I guess we can ignore it even in the context of my main question, sorry for being to verbose. What I found more interesting is, that cab doesn't try to re-install an installed package - already in the database too, as ghc-pkg output pretends - which is expected behaviour. The cabal system frontend obviously does trying to reinstall the package though. This seems like different model of reality...

This is not true. cab install re-installs some packages if necessary, unfortunately. That's why I recommend to use "cab install -n". --Kazu
