nmu xracer_0.96.9.1-6 . ALL . -m "Rebuild against freeglut 2.8" adequate reports adequate: ldd -r /usr/games/xracer: /usr/games/xracer: Symbol `fgDisplay' has different size in shared object, consider re-linking
As I understand it, fgDisplay is a private symbol, and the changes that were made in freeglut don't affect xracer; so it should be safe to binNMU it.
That said, xracer is a graphical game, so users are unlikely to see the warning, or pay attention to it, so I'm not sure if binNMUing is worth the trouble. Oh, and those users who do pay attention, will see tons of other warnings anyway: #153557.
