Can't install Criterion package on ghc ..

[Simon Peyton-Jones]

Can you check?  If it still happens with 6.12, please submit a bug report.
If 6.10 can't compile criterion, you might want to add a constraint to the Cabal meta-data.

| 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.
