# macports texlive can't find .sty file

I have texlive-fonts-extra installed:

$port installed texlive-fonts-extra The following ports are currently installed: texlive-fonts-extra @22691_0+doc (active)  According to https://trac.macports.org/wiki/TeXLivePackages, texlive-fonts-extra has doublestroke However, while compiling ($ pdflatex article.tex) a .tex file containing

\usepackage{mathtools, doublestroke}


I get

! LaTeX Error: File doublestroke.sty' not found.


I am using the correct copy of latex since

\$ which pdflatex
/opt/local/bin/pdflatex


What should I do to troubleshoot?

There is no doublestroke.sty package. The name to use is dsfont – egreg Mar 8 '12 at 22:38
Thanks @egreg, that worked! Wanna put it in an answer so I can accept it? – highBandWidth Mar 8 '12 at 22:44

I don't think there is a doublestroke package. According to the documentation for doublestroke you need

\usepackage{dsfont}

Alternatively, you can access the font as follows, but the package is the better option.

\documentclass{article}
\font\dsrom=dsrom10
\begin{document}
$\hbox{\dsrom N}=\{0,1,2,\ldots\}$
$\hbox{\dsrom ABCDEFGHIJKLMNOPQRSTUVWXYZ}$
\end{document}

 The usage of \font` in LaTeX is highly discouraged. Would you consider removing that part? – egreg Mar 8 '12 at 22:44 @egreg --- I posted too quickly, in a failed effort to get there before you! I have corrected my answer. – Ian Thompson Mar 8 '12 at 22:46 I had TeX Live Utility running. :) – egreg Mar 8 '12 at 22:49
