Bug#712304: glx-diversions: broken symlinks with libgl1-mesa-glx 9.1.3-6

[Sven Joachim]

Package: glx-diversions
Version: 0.3.0
Severity: serious

In Mesa 9.1 the libGL installation has changed, especially libGL.so.1 no
longer points to libGL.so.1.2 but rather libGL.so.1.2.0:

,----
| $ ls -l /usr/lib/i386-linux-gnu/libGL.so*
| lrwxrwxrwx 1 root root     14 Jun  7 21:37 /usr/lib/i386-linux-gnu/libGL.so -> libGL.so.1.2.0
| lrwxrwxrwx 1 root root     14 Jun  7 21:37 /usr/lib/i386-linux-gnu/libGL.so.1 -> libGL.so.1.2.0
| -rw-r--r-- 1 root root 354876 Jun  7 21:37 /usr/lib/i386-linux-gnu/libGL.so.1.2.0
`----

Installing glx-diversions in this situation leads to broken symlinks
(see Package-specific info below), and the glx-alternative-mesa package
silently fails to set up any alternatives, AFAICS.

Even after purging the glx-diversions package, broken symlinks remain:

I had to reinstall libgl1-mesa-glx (and libgl1-mesa-dev for the libGL.so
symlink) to fix that.
