There is very little documentation on enabling ccache on GNU/Linux. Here is a response from launchpad.net:

At the moment, I think the best way to enable ccache is to add "/usr/lib/ccache" to the front of your path. If you want to enable it for all users by default, change the PATH variable in /etc/environment.

Can someone give me more information on enabling ccache?
