I'd consider it highly unlikely that gluProject() doesn't work, you're probably misinterpreting the values it gives you - or the values you pass it.
I haven't ever used gluProject() but I reckon you have to pass world coordinates to it. So my first try would be to take the geometry, apply the appropriate modelview transform to it and pass it to gluProject().
