Comment 8 for bug 227480

For the opengl error on hardy it's an official bug who is corrected on ubuntu intrepid : https://lists.ubuntu.com/archives/intrepid-changes/2008-May/000220.html

I solve it by downloading the libqt4-opengl-dev package with synaptic and force the installation :
After you downloading the package
 - cd /var/cache/apt/archives/
 - sudo dpkg -i --force-overwrite libqt4-opengl-dev_4.4.0-1ubuntu1~hardy1_i386.deb

Enjoy
