[Haskell-cafe] cabal probems with binary/containers packages

It all started with this: Loading package binary-0.5.0.1 ... can't load .so/.DLL for: HSbinary-0.5.0.1 (dlopen(libHSbinary-0.5.0.1.dylib, 9): image not found) so I tried

cabal upgrade binary

Resolving dependencies... Configuring containers-0.2.0.1... Preprocessing library containers-0.2.0.1... Building containers-0.2.0.1... Data/IntMap.hs:182:7: Could not find module `Data.Data': it is a member of package base, which is hidden cabal: Error: some packages failed to install: binary-0.5.0.2 depends on containers-0.2.0.1 which failed to install. containers-0.2.0.1 failed during the building phase. The exception was: exit: ExitFailure 1 help.... Thanks, Brian
