Comment(by goldfire):
I ran into those two problems as well with the recent version of GHC, but
I thought the problems were local. Here are the fixes I used (package
maintainers already notified):
* For the syb problem, change syb.cabal to allow a greater range of
version numbers for the base package. I changed my file to allow {{{base
>= 4.0 && < 5.0}}} and it worked.
* For the mtl package, you'll need to edit Control/Monad/Error/Class.hs.
Add {{{catch}}} to the import list from {{{Control.Exception}}} on line
55.
I believe these were the only package-related problems I had, so these
fixes should allow you to proceed.
