libidn-0.5.15 kann nicht emerged werden und bircht ab mit:
Traceback (most recent call last):
  File "/usr/bin/java-config", line 14, in ?
    from java_config import jc_options
ImportError: No module named java_config
!!! ERROR: net-dns/libidn-0.5.15 failed.
!!! Function src_compile, Line 25, Exitcode 0
!!! You need to use java-config to set your JVM to a JDK!
!!! If you need support, post the topmost build error, NOT this status message.
Zuerst java-config emergen und danach libidn.
