Hi Karl,

I've tried to use xetex for a very minimal example, initially with a
font which should be ok, and completely failed.

Then I tried using xelatex with a PATH pointing to a not-installed
file in /tmp, both for fontspec and for setmainfont (based on an
answer at latex.org) but got absolutely nowhere.

Since Akira has passed the problem to the maintainer (thanks!) I
don't think I'm going to add a lot of value if I keep looking at
this.
