Note that there is a difference that my patch makes with an incomplete
installation: besides the obvious fact that libdispatch can be
compiled, you can also compile and run programs that do not use
blocks.  (I'm 99% sure---I don't have the broken system available
right now).

That said, I don't have any big qualm to keep this patch local or to
drop it altogether (most of it is just "sed" work).
