Scala Documentation is missing?

Hi,

I have downloaded and installed Scala 2.10.1 on my MacOS box. And, pointed this to Intellij 12. All is working well, but I am getting this error:

Library 'scala-library': invalid javadoc root

Furthermore, under scala-library -> Javadocs, it is showing "SCALA_HOME/doc/scala-devel-docs/api" is marked with RED.

Can you please tell how I can get this? I have downloaded scala docs from scala distribution site, but there is nothing in it with this name pattern (no scala-devel-docs/api there).

Thanks,
