That's a better solution!

The documentation on http://www.luarocks.org/en/Creating_a_rock  
suggests that external dependencies work like this:

external_dependencies = {
   LIBDATE = {
      headers = "libdate.h"
   }
}

But that should be "header" not "headers".

I agree that it's hard to know what the right thing is on OS X -  
perhaps it's as simple as suggesting what you did above in the  
documentation.  I'm trying make a rock for rima at the moment - once  
I've got through that, I might be in a position to have more of an  
opinion.

Cheers,
Geoff
