> [problems with cabal install yi]
Curious, I tried this out, on a Debian etch box with GHC 6.8.3.
"cabal update ; cabal install yi --global"
complained about needing alex >=2.0.something and <3.
Then "cabal install alex" happily installed alex version 2.2. Finally,
"cabal install yi --global" worked fine.
Is something amiss with cabal-install? Shouldn't it have automatically
installed alex? Or does it only do that with libraries, by design?
For that matter, "ghc-pkg list | grep -i alex" doesn't list anything,
after I cabal-installed it. How does cabal verify the prerequisite alex
version? (Or does it?)
I'm enjoying cabal since I've begun using it, but it's still somewhat
opaque to me.
