  Thanks for the tip, Daniel.

  I realize lnt will search for release build not debug build binary. But I
still cannot run lnt without problem. Here is the snip of test.log.

---
../llvm-3.0.obj/Release/bin/clang++ -o Output/build2.simple Output/build2.llvm.o

  I don't know why lnt cannot find clang++, clang++ is at the same directory as
clang is. Do you happen know what might goes wrong?

  Thanks!
