llvm dev - Nov 2012 - [LLVMdev] EngineBuilder::setEngineKind(EngineKind::Interpreter) error

I'm tinkering with various EngineBuilder parameters to see their effect on
performance.  If I do call EngineBuilder::setEngineKind() with
"Interpreter", I get an "Interpreter has not been linked in"
error message.  If I don't call setEngineKind() at all, my code works.

Note that I am calling InitializeNativeTarget() beforehand.

How can I try out the interpreter?
