[Haskell-cafe] Mac os x (Intel, 10.6.8) problem compiling yesod-core-1.1.7.1

Mon Jan 28 10:23:53 CET 2013

Hello

GHC version : 7.4.2

When I do a cabal-dev instal yesod-core, I get the following error:

Loading package blaze-builder-conduit-0.5.0.3 ... linking ... done.
Loading package hashable-1.2.0.5 ... linking ... ghc:
lookupSymbol failed in resolveImports
/Users/V3/windev/Haskell/Z/cabal-dev//lib/HShashable-1.2.0.5.o: unknown
symbol `_hashable_siphash24_sse2'
ghc: unable to load package `hashable-1.2.0.5'

Has anyone encountered the same problem?

Thank you

J-C
