Building prj40_prototype branch

I followed the instructions at:

http://projects.netbeans.org/proposals/prototype/index.html

specifically the "How to build it"/"stripped version"
and ran into 2 problems:

1: Error when building j2eeserver. Apparently it depends
   on a jar in libs (libs/j2eeeditor) but no dependency
   is specified in nbbuild/build.xml for this.
   Fix: add "all-libs/j2eeeditor" to list of dependencies
        for "all-j2eeserver".
        
2: Error when building xml/tree-edit. Compile classpath
   includes reference to 
    "${nbroot}/editor/netbeans/modules/ext/nb-editor.jar"
   which no longer exists.
   Fix: change to:
    "${nbroot}/editor/netbeans/modules/ext/editor-lib.jar"
    

It would be great if these problems could get fixed.
Or, are the instructions not correct? Am I supposed
to check out other modules (xml perhaps) from the 
prj40_prototype branch?

Thanks,
