Hi, I was motivated to install Sage from the Graph Theory example on
http://mvngu.wordpress.com/2009/06/24/sage-4-0-2-released/ (the
release tour). To run it I downloaded tkz-berge.sty and tkz-graph.sty,
but I still get the error Unknown environment "tikzpicture" on running
the example.
Doing some testing it was pointed out to me that \usepackage{tikz}
needs to be in the header of the tex file in order to avoid getting
this error when rendering the tex file manually. That appears to be
missing.
Where could I add that to get this example and other LateX Graph
Theory output to work?
Some details in case it is important, I'm running 4.02 on Ubuntu 9.04
and I had to follow the advice here:
http://groups.google.co.uk/group/sage-devel/browse_thread/thread/53ae33d0324d44/888575a45f3f43c6?lnk=gst&q=illegal+instruction#888575a45f3f43c6
because the binary packages used optimizations my processor doesn't
have and compiling from scratch failed.
Thanks
