Where does 0.9.10-2 come from? :)

Looking at the PPA, I'd suggest it should be burnt away quickly.

The PPA contains a package libosmesa6, which does not contain libosmesa6 
but libosmesa8 (libOSMesa.so.8). This is wrong. And this is the reason 
why desmume breaks: it expects libosmesa6 to contain libOSMesa.so.6.

The PPA should break every package depending on libosmesa6 (but not GTK 
stuff in general).

Please remove the PPA, install a proper MESA stack and enjoy a working 
desmume.

As an alternative: rebuild desmume for your broken environment:
sudo apt-get build-dep desmume
apt-get source desmume
cd desmume-*
dpkg-buildpackage -us -uc
sudo dpkg -i ../desmume*deb

Title:
  GTK version can't start because of libOSMesa.so.6; Glade version can't
  enable CPU recompiler and is very slow.

Status in “desmume” package in Ubuntu:
  New

Bug description:
  Hi folks,

  I think the GTK version of DeSmuME might need to be recompiled under a
  recent version of Ubuntu, because (when using 14.04 with Intel
  graphics), it's unable to start, throwing the following error:

  desmume: error while loading shared libraries: libOSMesa.so.6: cannot
  open shared object file: No such file or directory

  This package also installs a Glade version, but unfortunately it's not
  a viable alternative as it's missing many commandline arguments from
  the GTK version, crucially --cpu-mode=1, which runs the emulator in
  recompiler rather than the default interpreter mode, which is
  prohibitively slow.

  I'm afraid I wasn't able to compile it myself (I was able to build the
  CLI version before installing some GTK dev packages, but after that,
  make started failing) and don't know much about building deb packages,
  besides, so somebody might want to have a look here rather than just
  pulling in from sid.

  Thanks!
