It turns out (thanks to Darren for the debug info) that AFM files do not exist for all fonts in all current TeX distributions, so I have modified the pdf backend to not use them. This loses some information that is required by the pdf spec (such as the x-height and stem widths of the embedded font) but at least in some tests Preview.app and Adobe Reader don't seem to mind. -- Jouni K.
