There are a couple of licensing issues with the source release of 0.5.9.

First, as reported in http://bugs.debian.org/661340 the archive doesn't include the full contents of the bin directory as required to rebuild xmoto.bin. This is troublesome since the GPL requires the full source, i.e. the "preferred form for modification". It's easy enough to fix though, even for cases where rebuilding xmoto.bin is difficult since including the bin directory doesn't preclude shipping a pre-built xmoto.bin file as well.

Second, the SGI Free Software License B, version 1.1, as used by src/glext.h, might not be really free; at least the Debian project doesn't consider it to be DFSG-free (see http://bugs.debian/org/368560 for details). Version 2.0 of the license is OK, but the easier solution is simply to drop glext.h, which is possible with the following patch:
