Carbon Emacs won't start when installed in certain paths

[David Reitter]

Emacs (recent CVS build, Carbon) will not start when installed in  
directories with certain file names.
For example when I install the .app bundle in /Applications/Pour  
Développement, it refuses to run. When started from a terminal, the  
error messages I'm getting are

lucy:/Applications/Pour Développement dr$ Aquamacs\ Emacs\  
Yesterday.app/Contents/MacOS/Aqu*
Warning: arch-dependent data dir (/usr/local/libexec/emacs/22.0.96/ 
powerpc-apple-darwin7.9.0/) does not exist.
Warning: arch-independent data dir (/usr/local/share/emacs/22.0.96/ 
etc/) does not exist.
Cannot open load file: term/mac-win


(Not that the first two warnings are normal.)

This error obviously occurs before loading any user-specific  
settings, so I'm not sending the Emacs debug log.

N.B.: This build is compiled on OS X 10.3.9. I am testing on 10.4.9  
(PPC). The filesystem is the normal Mac filesystem (Mac OS Extended,  
Journaled).
