¡Ayuda! ¡No puedo averiguar cómo instalar un jdk!

[/usr/lib/jvm]$ su -c "yum install java-1.7.0-openjdk-devel"

Aquí he descargado manualmente algunas rpm, la última desde el sitio web de oracle:

[~]$ rpm -ivh java-1.7.0-openjdk-devel-1.7.0.19-2.3.9.3.fc20.x86_64.rpm

Depurar

Aquí hay algo de información de depuración:

[/usr/lib/jvm]$ yum search jdk

Requerimientos

I debe tener "jni.h"libjava.so"libhpi.so"lipverify.so"y"libjvm.so" incluido.

Hasta ahora he descubierto que estos NO tienen lo que necesito:

Versiones no deseadas (seguro):jdk1.7.0_06 <-Estoy sorprendido por esto, pero no tiene libjvm ni libhpijava-1.7.0java-openjdkjava-1.7.0-openjdk-1.7.0.9.x86_64java-1.5.0-gcj-4.4java-1.6.0-openjdkjava-1.7.0-openjdk.x86_64jre-1.5.0-gcjjre-1.7.0-openjdk.x86_64jre-openjdkjre-1.7.0jre-7u11-linux-x64.rpm java-1.5.0-gcj-1.5.0.0jre-1.5.0jre1.7.0_11jre-gcj

Y estos hacen:

Versiones deseadas (que yo sepa, podría haber más):jdk1.6.0_34-x86jdk1.5.0_22-x86java-6-openjdk

¿Puede alguien ayudarme a instalar jdk1.6 o java-6-openjdk por favor?
