(the 'impossible' happened) > (GHC version 6.10.4 for i386-unknown-linux): > idInfo co{v a9WB} [tv] This is definitely a bug in GHC, most likely related to type families and fixed in GHC-6.12.x If you can upgrade to ghc-6.12.1, that should solve this problem. If you need to remain on ghc-6.10.4, try installing an older version of criterion. You can do this with 'cabal install criterion-0.4.1.0' Criterion-0.5 is the first version to depend upon vector-algorithms, so any previous version has a chance of working.
