[lldb-dev] how to build lldb-mi on OSX?

[dawn at burble.org]

Can someone please tell me how to build lldb with MI support on OSX?
I follow the instructions at
http://www.codeplay.com/portal/lldb-mi-driver---part-2-setting-up-the-driver 
which say "the lldb-mi project is built as part of a full LLVM build" at
http://lldb.llvm.org/build.html, so I "build the lldb-tool scheme" in Xcode
but there's no lldb-mi anywhere, and lldb itself doesn't recognize the MI
commands.  I have rev.217536 checked out yesterday in case that matters.
What am I missing?  

Thanks in advance,
-Dawn
