Revision 2090: Tried building with Xcode 4.5.1 CL Tools - errors in i386/config/Makefile. Fixed them by eliminating "_nodep". Build completes - using new boot results in "Unable to start Symbols.dylib" and hangs.

I'll look into it. For now you can always disable the module system and compile the modules as built in.

disabling the module system and enabling any modules to be built-in breaks the build - undefined symbols when linking boot.sys. The only thing that succeeded was disabling the module system and disabling all modules. This generated a working boot.
