It works for me on 10.5.7 with:
gcc version 4.0.1 (Apple Inc. build 5484)

Please go into tools/llvm-config and use  "make ENABLE_OPTIMIZED=1  
VERBOSE=1".  That should show you how the dependency generation script  
is running, it takes a -why option.  Please send me the output off- 
list (it's large) and I'll see if I can help.
