It's a true shame.
I do not know about that, it seems common for Linux. I have never gotten BlitzMax to work properly on Linux which is why I gave BM away. PureBasic works with little effort on Linux, unfortunately, it is not the best solution for games. GLB is the only 3D solution for Linux.
My main GLB concerns are:
1. A previous post seemed to indicate that GLB programs would not work at all under Mandriva which is one of the most popular distros and my personal distro of choice.
2. Ubuntu is very good about bundling nice freeware games as part of the official Ubuntu distro. Unfortunately, with the hunting Toad had to do to find the runtime/lib needed for Ubuntu, it would lessen chances of getting something to be included with Ubuntu, as included programs need to work out of the box on a standard install.
