Thank you! This is helped for me too with 1.6.4 MCPC+.

The same problem.

OK, I have found the problem. When setting up a new MCPC+ server, the required scala libraries are downloaded except for the fact that the URL for the libraries are returning a 302 Found message. The library manager does not redirect to the new URL and instead simply stores the response as-is.
To fix, you need to manually overwrite the following files:

• libraries/org/scala-lang/scala-compiler/2.10.2/scala-compiler-2.10.2.jar
• libraries/org/scala-lang/scala-library/2.10.2/scala-library-2.10.2.jar

You can find the files from an installation of forge in your .minecraft folder or direct from scala-lang.org
This is an MCPC+ issue.

Ok. It works, thank you!

Thank You. I now see that scala-compiler library has very small size - 161 byte :D
