Actually I think this is not the right way to go.  It should be the
package manager on the host system that tells the build system where it
wants to keep stuff. =20

Certainly the library needs to inform the Haskell implementation where
it lives: that's what gtk-config does in essence, and what the GHC
package system does in a more general way.  But I don't see a need for
the Haskell implementation to tell the library where it should place its
files; indeed this is likely to conflict with OS package managers that
like to keep control of where files are installed.
