You probably should take Trent's advice and just use ActivePython (even
though he's been slacking and doesn't have a 2.1.2 build yet).

Seems like a useful error message to me.

xml.dom is written purely in Python so you aren't dependant on an
external C library.

Expat is a C library for XML parsing. It was written my James Clark, who
claims that it is the fastest parser in the world.

The problem is that expat is not a project run by the crew at
PythonLabs; it's a third-party product. I think that you will find this
to be the case with all scripting languages (it certainly is with
Perl/PHP/Tcl).

Maybe someone (not volunteering) should try to provide binaries for
novice Linux users?

Do you look for that file? Is it where you expected it to be?

Why don't you try something different and then tell us if it was easier
or not.
