[OS X Emacs] AUCTeX-XeTeX broken after switch to Carbon Emacs

[pdfinn at uwm.edu]

Hello everyone,

I've been running Emacs under the Mac OS X terminal for a while and managed to get
AUCTeX setup and working with La/XeTex thanks to help of some you on this list.  I
recently switched over to Carbon Emacs and now, when processing a XeTeX document I
get the following complaint:

This is XeTeX, Version 3.141592-2.2-0.995 (Web2C 7.5.5)
entering extended mode
! I can't find file `" -interaction=nonstopmode"'.

XeTeX then asks for an alternative file name.  Everything was working fine (and
still does) when Gnu Emacs is run through the terminal.  Any advice on what to
look into?

Thanks in advance,
Peter
