Dear Sirs, 


I download tikz.tds.zip <http://mirrors.ctan.org/install/graphics/pgf/base/pgf.tds.zip> from ctan and unzip it in /Applications/Context/context-osx-64/tex/texmf.

Next I run 
		mtxrun --generate
		context —make

My test  file contains:

####
\setupcolors[state=start]
\usemodule[tikz]   

\starttext

\starttikzpicture
 [node distance=4cm,
    place/.style={circle,draw=blue!50,fill=blue!20,thick,
                 inner sep=0pt,minimum size=6mm}]

    \node[place] (wat) {};
  \node[place] (wag) [below=of wat] {};

\stoptikzpicture

\stoptext
####


The log is:

This error message was generated by an \errmessage command, so I can't give any
explicit help. Pretend that you're Hercule Poirot: Examine all clues, and deduce
the truth by order and method.


Anybody has a clue how to fix this?

Thanks to all.
