Installing Pandora add-on??

Anyone able to install Pandora add-on to the latest official release of XBMC on the ATV2? I found a zip file hosted online (of course, I don't know that it is 100% ok), and tried to install from zip file like done w/ bluecop repository, however, I get a failure when trying to install it......anyone have it working and willing to give some details of installation? thanks in advance
-m

resolved it.....for some reason the zip file must have had an extra layer....i pulled out the file from the zip archive and renamed it with a .zip extension.....that file installed just fine
