Aha. The fonts appear to have been moved at some stage.
I had deleted the font names database in

/Users/will/Library/texlive/2010/texmf-var/luatex-cache/generic/names/otfl-names.lua

but when that was re-created it was still using the old temp-xb-zar*.lua files. I think these temp-*.lua files need to be kept up-to-date more aggressively.
