First you must download the GPL code from the URL found in the forums.
Then, if you're running on an 64bit OS, you may need to patch m4 and bison.
Patching Tools
You will be creating patches directories in tools/m4/ and tools/bison, and adding the following files.
cd $TOOLCHAIN_DIR
mkdir tools/m4/patches tools/bison/patches
tools/m4/patches/010-stdio.in.h.patch
--- a/lib/stdio.in.h
+++ b/lib/stdio.in.h

Compiling Packages
You can use the instructions at [1]
For example for recompiling udev (a simpler package without dependencies):
make tools/install
make toolchain/install
make package/udev/compile
After the first time, only the last command needs to be run. Then the package can be found in bin/g2/packages. You can also do make menuconfig and choose the packages you want to build, then just run make package/install.
