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!
