I am not sure if this is just a specific problem on Leopard 10.5.6 or on any other platform too

What steps will reproduce the problem? 1. Following the building instructions on http://code.google.com/p/iphone-dev/wiki/Building 2. Go to the last phase where the compiler is build 'Configure and make LLVM-GCC. Make sure that $LLVMOBJDIR and $HEAVENLY are set per the instructions above. ' 3. The third command starting with '../../llvm-...' has a wrong parameter

The specific wrong parameter is: --enable-llvm=llvm-config --obj-root

This is wrong, it should use the previously set environment variable: --enable-llvm=$LLVMOBJDIR

With this little modification the build process of building the compiler can start without problems.

I have no rights to make the apropriate changes on the wiki page, so I hope a admin/developer of the iphone-dev team can make set change in the wiki page.
