As I wanted to test Scala 2.9.2 on my gentoo system I tried updated the package but ended up with this error. I can't figure out where the problem may be:

The following eix output may help:

Try this:

emerge -1 java-config java-config-wrapper

It rebuilds Java environment configuration tool and java-config wrapper.
