If the libraries are already installed but in a non-standard location then you can use the flags --extra-include-dirs= and --extra-lib-dirs= to specify where they are.

Are you sure that you installed wxWidgets 2.9 and didn't just compile it 
from source? It looks like cabal can't find the wxWidgets libraries on 
your system.
