What does people normally use to stress test their GPU on ubuntu 12.04?

I tried installing Phoronix Benchmark suite ubuntu .deb but it tries to install freeglu3-dev and at the same time complains about

$ phoronix-test-suite benchmark pts/opencl

The following dependencies are needed and will be installed:

• freeglut3-dev

This process may take several minutes. Reading package lists... Building dependency tree... Reading state information... freeglut3-dev is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 90 not upgraded.

There are dependencies still missing from the system: - OpenGL Utility Kit / GLUT

1: Ignore missing dependencies and proceed with installation. 2: Skip installing the tests with missing dependencies. 3: Re-attempt to install the missing dependencies. 4: Quit the current Phoronix Test Suite process. Missing dependencies action: 4

so even if it is installing freeglu3, it still complains about missing GLUT. You can't win against GLUT it seems

So, what does people use for this? i mean, really, because i have tried googling for an hour and it is not paying up

Thanks!
