GLUT uses XmuLookupStandardColormap from libXmu. libXmu requires
libXt, which in turn requires libSM.

As that's the only Xmu function which GLUT uses, I would have thought
that it would be worth making the effort to remove that particular
dependency from GLUT.

Insofar as it's a bug, it's in the dependency list for GLUT. 
Ultimately, the correct dependency list for the Haskell GLUT package
is "GLUT, plus whatever GLUT happens to require on your particular
system". But I don't know whether the dependency list can be generated
dynamically.
