Hi Don,

A good question. Mozilla only provide 32-bit XulRunner applications by 
default, you you'll need to install the necessary 32-bit compatability 
libraries on your Linux machine, i.e. for Ubuntu it's something like:
sudo apt-get install ia32-libs ia32-libs-gtk

Then you should be able to run the example. You can check the 
dependencies using something the following commands, there should be no 
missing dependencies:
$ cd pyxpcom_gui_app/xulrunner
$ LD_LIBRARY_PATH=. ldd ./xulrunner-bin

It is possible to use a 64-bit version, but you'll need to compile this 
yourself (or find somewhere that provides these x86_64 versions). Note 
that the PythonExt project does not offer Python bindings for x86_64 
either (it's on my todo list), you can compile the PythonExt part 
yourself as well if you need a 64-bit version.

Cheers,
Todd
