In Section 4.1 of the ADT manual, we should add a NOTE saying that it is not recommended to install the Eclipse form Ubuntu/Fedora package repository. Instead the user is recommended to install the eclipse from Eclipse official site as mentioned in Section 4.1.1. Besides, the example in Section 4.1.1 is still using "eclipse-SDK-3.7.1-linux-gtk-x86_64.tar.gz" which should be "3.7.2".
I have added the note and fixed the example tar file name as suggested. See http://www.yoctoproject.org/docs/latest/adt-manual/adt-manual.html#setting-up-the-eclipse-ide for the updated section. Scott
