I wrote: > http://hackage.haskell.org/trac/ghc/ticket/4812 It looks like this problem happens when you upgrade or reinstall the directory package (any version) after upgrading the unix package to version 2.4.1.0 on Mac OS X. Note that the directory package does depend on unix or Win32, as obviously it must. That dependency can be seen in directory.cabal, even though it does not show up on hackage. Thanks to Simon Marlow for clarifying that point. So a work-around for this problem is: cabal install --reinstall --constraint='unix == 2.4.0.2' directory If you originally upgraded or reinstalled directory using the --global flag, you must add it to the above also. Thanks to Duncan Coutts for this work-around.
