Hi Kaja. This is not an answer from the official group, but I am used to linux so i ve seen this error before. This particular error is printed out when the GL installation doesn't include the GLX extensions in an X window environment (GLX not found. Aborting.). Check to see if there are any GLX packages available on this platform that are missing.

Kind regards Haakon Ramsland Hol
