I am trying to install ytableau.sty, following the directions here and here, and in the ytableau README. I am running TexShop 2.47 on OS X 10.6. Here's a walkthrough of what I've done, although I suspect I may have gone wrong early on.
First of all, I don't already have it:
\documentclass{amsart}
\usepackage{ytableau}
\begin{document}
\end{document}
produces
! LaTeX Error: File `ytableau.sty' not found.
Downloaded ytableau.ins from CTAN, ran latex ytableau.ins, created directory ~/Library/texmf/tex and copied resulting ytableau.sty file to it. Test file now produces
LaTeX Warning: You have requested, on input line 173, version
`2011/06/02' of package pgfopts,
but only version
`2008/06/26 v1.0 LaTeX package options with pgfkeys'
is available.
! Undefined control sequence.
l.174 \ProcessPgfPackageOptions
{/ytableau/options}
Repeated process to install the June 2, 2011 version of pgfopts.
I still get the same error message. I've tried putting pgfopts in a few different places, namely ~/Library/texmf/tex, ~/Library/texmf/tex/pgfopts, ~/Library/texmf/latex and ~/Library/texmf/latex/pgfopts, but either LaTeX is still finding the old version or that wasn't the actual problem.
~/Library/texmf/tex/latex/<packagename>/. To test if they are being found, runkpsewhich <packagefile>(for example,kpsewhich pgfopts.sty). – Andrew Stacey Sep 05 '12 at 15:14pgfopts. In fact, I received a bug report relating topgfoptsversion 1.x, and it seems that version 2.x is really significantly different. So you'd have had an error either way :) – Ryan Reich May 02 '13 at 06:28
