i tried to install wxGeneric and need syb-with-class. i got the package from hackage. configure runs fine, but when i build i get:
Data/Generics/SYB/WithClass/Instances.hs:11:7: Could not find module `Data.Array': it is a member of package array-0.1.0.0, which is hidden
but array-0.1.0.0 is installed, as shown later. what can be wrong? why is an installed package complained about as hidden?
thanks for help!

Probably an old .cabal file where array is not yet listed among the build-depends. Cabal hides all packages not listed there when building. Try adding array to that list and building again (the same may be necessary for some other packages which were split off base). Cheers, Daniel
