[Building Sakai] mvn build hangs with Rhino classes (js.jar) not found

[Richwine, Brian L]

Hi,

I am attempting to build the third 2.7.0 beta tag following the Development Environment Setup Walkthrough on OS X 10.6.2, and when running maven it hangs after the following message:
   ------------------------
   TESTS
   ------------------------
   Running org.sakaiproject.portal.charon.test.http.AnonPortalTest
   Rhino classes (js.jar) not found - Javascript disabled

I'm a newbie, and had initially had success with compiling 2.6 on Ubuntu, and just set up this mac.

Thanks for any suggestions,
  Brian
