For example, HAIFA (http://www.dcs.shef.ac.uk/~simonf/HAIFA.html) requires SYB3, which i couldn't find on the web, so, it being a separate package from the base didn't solve the problem.
of course, to solve this problem, one should also upload his libraries to hackage :) this may be not possible for syb3 because it's closely coupled with ghc - i don't know
As far as i understood, the SYB3 is considered no longer necessary with GHC6.6 extensions. Being unnecessary doesn't make the packages based on it work, though. Another example is hs-plugins (http://www.cse.unsw.edu.au/~dons/hs-plugins/). It still doesn't work with GHC6.6, as far as i know, and as such is simply unusable, despite all its greatness. The same goes to your compression library (http://www.haskell.org/haskellwiki/Library/Compression), which i couldn't build with recent GHC under CYGWIN. That is the point, i think, while FPS should be in the base, in a jurisdictional way. It might install as a separate package, but it should be maintained as the part of the base...
