It compiles fine but the load fails with...

Can anyone explain this and help me with what I'm not doing or not doing right?

Blocks are only available on Mac OS X 10.6. Make sure your project's SDK is set to 10.6 (or alternatively "Current Mac OS" if you're compiling on a 10.6 machine). Blocks are currently unsupported on Mac OS X 10.5 and iPhone OS.

_NSConcreteGlobalBlock comes from CoreFoundation. You could get this error if you weren't liking to CoreFoundation, but presumably you are linking to CoreFoundation by way of Cocoa.framework. (Otherwise you'd have trouble with NSNumber and NSTextField too.)
