[Impact]
* Building mesa and xserver-xorg-video-nouveau from source with the updates pocket enabled will not work correctly.
[Test Case]
* Build and run those affected packages, they should build correctly and still link against libdrm_nouveau.so.1
[Regression Potential]
* Theoretically just a rebuild, so when I initially pushed the libdrm update I didn't want to risk pushing the updates to those packages since theoretically they should otherwise be identical. I never broke abi compability, so this would just be a rebuild.
* Build logs should be looked over to ensure that no strange things pop up.
[Other Info]
* libdrm moved to a new abi, but retained the same soname with a small bump. This means that the old mesa and xxv-nouveau packages need to look for libdrm-nouveau1's package config now, which contains the correct information.
* libdrm_nouveau.so.1 -> old abi, link against it with -ldrm_nouveau1, and use libdrm-nouveau1 pkg-config
* libdrm_nouveau.so.2 -> new abi, libdrm-nouveau pkg-config and -ldrm-nouveau should be used.
[Original bug report]
It looks like the libdrm_nouveau library has split into version 1 and version 2, but the mesa package shipped with Ubuntu precise hasn't been updated to build with the updated packages.
apt-get source mesa
pbuilder-dist precise build mesa_8.0.4-0ubuntu0.3.dsc

make[7]: *** [nouveau_vieux_dri.so] Error 1
Looks like an ABI break in libdrm-nouveau, which resulted in a SONAME bump from libdrm-nouveau.so.1 to libdrm-
