[Pharo-dev] Running on Ubuntu?

Hey guys, just wanted to show others our cool stuff.. but faced strange problem: ~/projects/pharo$ ./pharo-vm/pharo pharo.image could not find display driver vm-display-X11; either: - check that /home/sig/projects/pharo/pharo-vm//vm-display-X11.so exists, or - use the '-plugins <path>' option to tell me where it is, or - remove DISPLAY from your environment. Aborted (core dumped) i tried to download manually, tried to use command-line install script .. but same result: - it doesn't seem to want to pick up the x11 driver and so, fails to start.. needless to say, that driver exists, lies there right at the location of vm binary etc etc yadda yadda.. anyone knows what going on? -- Best regards, Igor Stasenko.
