Fascinating. I don't see this error on either Mac OS X or Linux.  I 
happen to have clang checked out into llvm/tools; maybe my SAFECode 
clang build is picking something up from the original clang.

I'll do a clean build with just LLVM, poolalloc, and SAFECode on Mac OS 
X and see what happens.

Does changing the line to CLANG_LEVEL = ../.. work also?
