Sorry, I know nothing about clang. My first guess is that you are
missing a library on the command line. Is NSConcreteGlobalBlock defined
in a library or in something that clang automatically links? If you are
proficient with `nm' you can try searching where NSConcreteGlobalBlock
is defined.

I would ask on the clang mailing list too.
