Can you tell me the best way to Gentoo all of this? I've now got: # java-config -L The following VMs are available for generation-2: 1) Sun 32bit JRE 1.6.0.07 [emul-linux-x86-java-1.6] 2) Sun JDK 1.5.0.16 [sun-jdk-1.5] *) Sun JDK 1.6.0.07 [sun-jdk-1.6] and dev-java/sun-jdk in my world file, and it wasn't there before. Also, emerge world wants to install virtual/jre-1.6.0 and virtual/jdk-1.6.0. Should I un-emerge sun-jdk-1.5? - Grant
