# How to use \phase on MacTeX?

I'm trying to obtain the effect of the \phase command as discribed in the The Comprehensive LaTeX Symbol List (page 70)

I've added the amssymb and pict2e packages correctly (no errors on adding packages), but it keeps saying "Undefined control sequence." when I try to compile.

I'm sure I'm missing something very basic. Is there another package to add? Wich one? Or it just does not work on MacTeX?

The documentation suggests \usepackage{steinmetz}

\documentclass{article}
\pagestyle{empty}
\usepackage{steinmetz}
\begin{document}
$\phase{abc}$
\end{document}

Guess I read something wrong. Thanks, Boris! –  Sergio Moura Nov 18 '11 at 19:20
Please use reasonably sized figures. I have replaced the one you used. –  Peter Grill Nov 18 '11 at 19:37
