I am running a recently updated TeX Live 2011 on a Mac (OS X 10.7 Lion). I wanted to use the XITS fonts, but the following file generates errors when processed with xelatex:
\documentclass{article}
\usepackage{unicode-math}
\setmainfont{XITS}
\setmathfont{XITS Math}
\begin{document}
Text $x+y=\sqrt{z}$
\end{document}
I'm including the relevant (I think) output below. Any ideas what is going on?
kpathsea: Running mktextfm XITS
/usr/local/texlive/2011/texmf/web2c/mktexnam: Could not map source abbreviation X for XITS.
/usr/local/texlive/2011/texmf/web2c/mktexnam: Need to update /usr/local/texlive/2011/texmf-dist/fonts/map/fontname/special.map?
mktextfm: Running mf-nowin -progname=mf \mode:=ljfour; mag:=1; nonstopmode; input XITS
This is METAFONT, Version 2.718281 (TeX Live 2011)
kpathsea: Running mktexmf XITS
! I can't find file `XITS'.
/Library/Fonts
(or wherever regular Mac fonts are installed in Lion) (I'm still using 10.6).
