[tex-live] I must be missing something with TeX...

[Karl Berry]

    Usually you can add the ttf/otf font to a directory below
    /usr/share/fonts, run fc-cache and then it is available for XeTeX.

Or access ttf/otf by filename, rather than font name, and then you don't
have to do the system font install.

The downside is that then fontspec can't automatically get the /B and
other variants.  Will and I have thinking about ways to deal with that.
