  I’m using TeXLive 2011 via MacTeX, and I keep my packages updated. I’m trying to start simple with tkz-graph.When I use the following code, copied directly from the tkz-graph documentation:\begin{tikzpicture}\GraphInit[vstyle=Classic]\Vertices[Lpos=90,unit=2]{circle}{A,B,C,D,E,F} \end{tikzpicture}I get the errorLatex Error: ./myfile.tex:26 Package xkeyval Error: `unit’ undefined in families `vertex’.And when I try this:\begin{tikzpicture}\GraphInit[vstyle=Classic]\Vertices{circle}{A,B,C,D,E,F} \end{tikzpicture}The output is:Clearly something is very wrong, but what is it? How can I fix this?Edit: Minimum breaking example:\documentclass{article} \usepackage{tkz-graph}\begin{document} \begin{tikzpicture}\GraphInit[vstyle=Classic]\Vertices[Lpos=90,unit=2]{circle}{A,B,C,D,E,F} \end{tikzpicture} \end{document}And more information:$ tlmgr show tkz-graph package: tkz-graph category: Package shortdesc: Draw graph-theory graphs. longdesc:
