Running Cross-Compiler Version of GCC on a Mac

Folks,

I’m trying to run the cross-compiler version of gcc on my Mac. I downloaded the file

arm-2007q3-macosx-20080828.tar.bz2

from the MacOS X/ x86 section of http://elinux.org/BeagleBoardFAQ, then installed into a temporary directory on my desktop. The path to this gcc cross-compiler on my Mac is

~/Desktop/temp/arm/arm-none-linux-gnueabi/bin/gcc

When I try to run gcc with the command ./gcc, I get the following error:

gcc: error trying to exec ‘cc1’: execvp: No such file or directory

The program cc1 resides in the following directory:

~/Desktop/temp/arm/libexec/gcc/arm-none-linux-gnueabi/4.2.1

Should I be compiling with a certain flag for gcc to find cc1?
