I'm thinking there may be additional 32-bit packages necessary then (I'm
not sure which package).
Not sure about Ubuntu 8.10 (it's still alpha). I'm using a Ubuntu 8.04
x86_64 machine and my dependencies list the following for the latest
32-bit build of XulRunner:
$ LD_LIBRARY_PATH=. ldd ./xulrunner-bin | grep libxcb
libxcb-xlib.so.0 => /usr/lib32/libxcb-xlib.so.0 (0xf6493000)
libxcb.so.1 => /usr/lib32/libxcb.so.1 (0xf647b000)
