 When building openvrml with `+js_spidermonkey`, `-I${prefix}/include/js`
 needs to be added to `CPPFLAGS`.

 Conceivably, `JS_CFLAGS` could be used for this instead. However, note
 that if `JS_CFLAGS` is '''not''' set, `configure` will set it to
 "`-DXP_UNIX -DJS_THREADSAFE`". This is ''probably'' correct for MacPorts'
 SpiderMonkey; but if it's not, `JS_CFLAGS` should be set to override it.

 So, assuming `JS_CFLAGS` doesn't need to be modified for some other
 reason, it should be sufficient to apply this `-I` flag in `CPPFLAGS`.
