Generated rdoc documentation is incomplete

Hello.
I download ruby to the ruby-build directory from cvs, install it and
want to make a html documentation.
yuray@keeper:/host/p3/b/ruby-build$ ruby --version
ruby 1.9.0 (2005-11-18) [i686-linux]
yuray@keeper:/host/p3/b/ruby-build$ rdoc --all --op /tmp/ruby-doc

All is seems OK.
But opening file:///tmp/ruby-doc/index.html in the browser I can not
find documenation about
drb (drb directory is absent in the Files section).

If I run rdoc in the lib/drb, then it is be generated.
yuray@keeper:/host/p3/b/ruby-build/lib/drb$ rdoc

                     extserv.rb: mc....c...
                         acl.rb: cc....c.......
                         drb.rb:

Why rdoc not make the documentation for drb from topdir ruby sources ?
How can I force the rdoc make the ALL documentation ?

Remove all “.document” files from any directories (e.g. the lib and ext
directories).

Search the list for “rdoc” for more info - this question was answered
recently.

Thank you for guidance.
