Hi, I have updated to texlive 2012... unfortunately... texlive-pgf seems to be too old. a simple document like this \documentclass{article} \usepackage{tikz} \begin{document} \end{document} fails with (/usr/share/texmf/tex/generic/pgf/math/pgfmath.code.tex (/usr/share/texmf/tex/generic/pgf/math/pgfmathcalc.code.tex (/usr/share/texmf/tex/generic/pgf/math/pgfmathutil.code.tex) (/usr/share/texmf/tex/generic/pgf/math/pgfmathparser.code.tex) (/usr/share/texmf/tex/generic/pgf/math/pgfmathfunctions.code.tex (/usr/share/texmf/tex/generic/pgf/math/pgfmathfunctions.basic.code.tex ! Package PGF Math Error: The function `add' already exists. See the PGF Math package documentation for explanation. searching the web they claim the problem was solved in the last cvs... http://sourceforge.net/mailarchive/forum.php?thread_name=F90783B3-F609-4D78-B89C-420BA445D4B1%40virginia.edu&forum_name=pgf-users is there any chance to get it updated?
