Mac OS X build fails

[Martin Jourdan]

I am new to using/building Emacs on MacOS X (although I am not new to 
Emacs in general). I just downloaded the latest Emacs sources from the 
CVS repository, using the instructions from 
<http://members.shaw.ca/akochoi-emacs/>, and started to build it on my 
MacOS X 10.2.5.

"make bootstrap" fails with the following messages :

./temacs --batch --load loadup bootstrap
Loading loadup.el (source)...
Using load-path (/Users/martin/Documents/Work/x-install/emacs/lisp

make: *** [bootstrap] Error 2

Any idea on what causes that?

Many thanks in advance.
