UE4 now loading in Linux

I recently built UE4 on ubuntu 15.10. It got compiled fine without any error.

The editor crashes at 45% load at the splash screen.

I have attached the crash logs.

I am currently trying to build ue4 for like the 3rd attempt on Kubuntu 15.10 and it seems have failed the last 2 times, this error keeps popping up

I made sure I had all the dependence. and followed the wiki. only thing i changed 3rd time was double check apt-get for latest versions. and remove -b 4.9 from git pull down.
