I seem to be having trouble using GHC 6.8.2 and OS X (10.5). It seems that any use of anything from Data.Map results in a link error like

In my experience, you will get this error if you have some libraries which were built against an older version of Data.Map and then you upgraded to the new Data.Map without rebuilding those libraries. Or, if you just have some .o/.hi files in your local directory that were built against the old Data.Map. Have you tried creating a very simple new project like:

module Main where

import Data.Map

main = print (empty :: Map Int Int)

$ ghc --make Main.hs -o test If that fails, then the problem is likely with your GHC 6 installation itself, not some stale third party library. Have you previously installed GHC 6 on this machine? If so, perhaps the old version was not completely removed and the compiler is getting mixed up. Alternatively, perhaps the new version requires you to install some extra package to get all the libraries, instead of just the core libraries ? Looking at the binary distribution page, that does not appear to be the case. j.
