Thank you very much. Adding these lines to scenegraph.cabal makes it work: other-modules: Graphics.SceneGraph.Matrix Graphics.SceneGraph.MySTM Graphics.SceneGraph.ReadImage Graphics.SceneGraph.TGA Graphics.SceneGraph.Utils I've contacted the author, who seems willing to fix the "official" package -- although he'd like to find someone else to maintain it.

I'd like to get the scenegraph package (http://hackage.haskell.org/cgi-bin/hackage-scripts/package/scenegraph) to work, but am encountering linkage errors. [...] Also, I notice that in the cabal file for scenegraph, the list of exposed modules
Exposed-Modules: Graphics.SceneGraph, Graphics.SceneGraph.Basic, Graphics.SceneGraph.Vector, Graphics.SceneGraph.Render, Graphics.SceneGraph.SimpleViewport, Graphics.SceneGraph.GraphViz, Graphics.SceneGraph.Library, Graphics.SceneGraph.Dump, Graphics.SceneGraph.Textures

That basically means that the scenegraph package is broken. ;-) Internal modules have to be listed in "other-modules:", a section the Cabal file doesn't contain. As a quick fix, you can add all missing modules in this section, but this should of course be fixed in the official package, too.

Cheers, S.
