What graphics stack are you using, in particular your kernel and Mesa
driver? Running `reportbug --template ioquake3` will summarize the most
relevant packages.

It looks as though the problem might be that your driver only provides
GLSL 1.20 (either on your hardware or in general), whereas the hitCube()
function introduced between 09166ba and e5da13f assumes GLSL 1.30
or later.
