You appear to have a gcc installed somewhere that is not configured to support objective-C. Make sure to remove it from PATH so that the system gcc supplied by Apple is found instead, which has objc support compiled in. The output produced by gcc -v should then have "--enable-languages=c,objc,c++,obj-c++" somewhere in it. Then start a new install.

That should not be the problem, as Joyce is trying to build the Cocotron cross-compiler gcc, which doesn't require Objective-C. There is a long-standing problem with compiling gcc using Apple's standard llvm compiler, hence my tutorial's instructions to use another compiler instead to build gcc for Cocotron. Joyce appears to be using the "HPC" (http://hpc.sourceforge.net/ ) gcc build, which has worked for me in the past.

Joyce, are you on Mountain Lion? If so, that might be the issue: the HPC GCC installer provided in my tutorial is perhaps not compatible with Mountain Lion (10.8 was not out when I wrote the tutorial).

On the HPC GCC page, they appear to have a build specifically for Mountain Lion:

http://hpc.sourceforge.net/

It's the download labelled "gcc-mlion.tar.gz (4.8)". You could install this version of GCC and see if it works.
