w3 and css

[Andrea Crotti]

I think I never actually saw w3 working on my machine, so I finally wanted to 
get it working.

I downloaded from the git repository here
http://www.gnu.org/software/w3/

configured an compiled.
But when I try to run it I get this backtrace:

So it finds the default css (which I didn't touch) and doesn't like the syntax 
of it.
Anyone else has the same problem? Am I missing something?
