Changed the location of the Steam root directory from whatever it was to $REAL_DEBUG_HOME/Steam/SteamApps etc.
Note that I have not had a single Phoronix 3D benchmark ever work out of the box. I've had to edit every single script so far.
I've managed to get TF2, Portal, and supertuxcart working. Doom3 will not work (looks like missing .pak file)
