[XeTeX] xelatex and the TL2009 portable solution with a usb-stick

[M. Niedermair]

Hi,

I try the protable version of TL2009 with xelatex.
Now I have the problem, that the font libertine (loaded over the 
operating system) is not found.

Is there a way, to say Windows or xelatex (no Administratormode and no 
way to change any registry entry) that the Font, that the operating 
system is loading, has to be found in a special directory (on the 
usb-stick)?
