It's interesting to hear if Debian comes with GLU by default. (It is really just GLU needed by GLEW that is missing here.)
However, I guess this is mostly a policy question for U++ POSIX installation script maintainers to decide, if OpenGL dependencies required for GLCtrl should be included in the script or not. I.e. if it is enough to only satisfy dependencies for TheIDE and umk, or alternatively for all packages included in uppsrc.
Thanks and best regards,

Not, for simple reason: there are too many variations, it is hard enough to get theide requirements half-right...
