I link with:

clang++ -headerpad_max_install_names -arch x86_64 -o qt-checker main.o 
-L/data/clang-llvm/llvm-3.1-install/lib -lpthread -lm -lLLVMCore -lLLVMSupport 
-lclangTooling -lclangAST -lclangFrontend -lclangSerialization -lclangSema 
-lclangAnalysis -lclangBasic -lclangEdit -lclangLex -lclangParse 
-Wl,-undefined,dynamic_lookup -L../checkers -lcheckers

I get:

 dyld: lazy symbol binding failed: Symbol not found: 
__ZN5clang6driver6DriverC1EN4llvm9StringRefES3_S3_bRNS_17DiagnosticsEngineE
  Referenced from: /data/git/qtcheckers/app/qt-checker
  Expected in: dynamic lookup

Etc. For clang plug-ins it works, but apparently not for tooling executables...
