This is definitely a cups problem.  They are assuming that blocks support (a 
compiler feature) implies the presence of libdispatch (a library).  I don't 
know if libdispatch has been ported to OpenBSD.

I think the -base configure checks for the presence of libdispatch because we 
use it for parallel array operations, so the best thing to do is use that macro 
to conditionally #undef __BLOCKS__ before including cups.h
