How do I install yi?
get it from hackage. Configure, compile and install yi as you would do for any other Cabal package.
Setup.hs does not compile!
You need to use Cabal version 1.2.3. To make sure you use it, do:
   ghc -package Cabal- --make Setup.hs
   ./Setup configure ...
Setup configure fails with
"Setup.hs: Package yi-0.3 can't be built on this system."
it means that you have no UI package available. You need vty or gtk2hs installed. Get them from hackage.
I get "No instance for (RegexLike Regex B.ByteString)"
It *could* be that the regex-instance in your bytestring package ther is only an instance for the newer regex-package. That is, your newly installed regex-posix- doesn't "see" the ByteString instance, because it was only defined for the regex-posix-0.93.1 package that bytestring knew about when it was built. This is yet another aspect of a known, tricky Cabal bug.
