Hey Chris,

The last time I had that problem with vm-display-X11 I ran through a similar odyssey. I ended up running the squeak-vm through strace and it turned out to be libGL.so.1 (IIRC), the 32-bit version of it. Once I created a symbolic link in /usr/lib32/ everything was fine.

Hope this helps,
Markus
