missing spidermonkey development headers

Hi, I am porting my project to Darwin and I have encountered a problem with the Spidermonkey port. It does not install all required headers. After "port install spidermonkey" I only had jsapi.h and jsautocfg.h, in reality there should be much more (you can easily see that jsapi.h includes "jspubtd.h" and so on). Problem encountered on Darwin 7.9.0 Any chance this will be fixed? Thanks, Jin
