Building on OS X

I'm having some problems building boost 1.25.1 with gcc on Mac OS 
10.1. I first tried Jam 2.3.5 from the The FreeType Project 
SourceForge site with the following command line:

jam -sBOOST_ROOT=tools/build/allyourbase.jam -sTOOLS="gcc"

I got these warnings:

warning: unknown rule project-root
warning: unknown rule subinclude
warning: unknown rule subinclude
warning: unknown rule subinclude
warning: unknown rule subinclude
...found 7 targets...

and the build quit. Then I noticed the tools/build/jam_src folder so 
I went ahead and built that version of jam by typing "jam" in that 
folder. I copied the new tool into /usr/bin and tried to build boost 
again and got some new errors:

boost-build.jam: No such file or directory
don't know how to make all
...found 1 target...
...can't find 1 target...

Anyone know what's going on here? Do I have to set some environment 
variables? BTW both versions of jam print the following when I use 
the -v option:

Jam/MR  Version 2.3.2.  Copyright 1993, 2000 Christopher Seiwald.  OS=MACOSX.
