[luatex] unicode-math: Undefined control sequence., <argument> \um_prime_single_mchar

[Graham Douglas]

Dear All

Firstly, a huge THANK YOU to Will for his incredible
energy and expertise in writing fontspec and unicode-math.

In summary, I build LuaTeX from source and run it on
Windows Vista with a custom runtime environment (texmf.cnf)
--- hand built (ie hacked) from scratch.

Anyway, it all works fine. I have fontspec working but just
downloaded unicode-math and have hit a problem with it.

Here is my command line

$ luatex --fmt=pdflatex fs.tex
This is LuaTeX, Version beta-0.60.1-2010060119

Here is a  minimal test file

\documentclass[12pt]{article}
\usepackage{unicode-math}
\begin{document}
\setmathfont{Cambria Math}

\end{document}

Output of the run is below.

Any ideas what is tripping me up here?

I'm not an expert is this area at all -- so
simpler explanations would be great :-)

Many thanks in advance

Warm regards

Graham
