"Error in main glxinfo is not installed. Please install mesa-utils package" when trying to install PlayOnLinux

I am currently trying to install League of Legends using PlayOnLinux, but every time I do I get this error:

Error in main glxinfo is not installed. Please install mesa-utils package

What should I do to fix this? I am using Ubuntu 12.10.
