The problem with this last one is not --deep. It is --update. 

When you issued emerge --update --deep world, it found that according
to the installed ebuild portage kept, that 

  a) OpenOffice does not need rebuilding-- since there is no update
according to version number.
  b) none of the dependencies installed by openoffice needs
rebuilding, since there is no update.

But when you issued emerge --deep openoffice, you asked for portage to
consider rebuilding openoffice, which now looks at the ebuild in the
tree, which, as you noted, is different from the ebuild that you
emerged months ago. As such, any new dependencies that differs between
the two ebuilds and any build-time dependencies will need to be
satisfied. 

And my suggestion would be to just ignore this little thing with
openoffice. If open office runs, and that the ebuild change is minor
enough to not get a new release number, then you can probably wait
until the next release of openoffice to worry about updates.
