I just had to remove keywords for the arches in CC from dev-ruby/text-format, due to a new dependency dev-ruby/text-hyphen. The latter is currently only keyworded for ~amd64 and ~x86. Please test both text-hyphen and text-format and add back your keyword to both ebuilds if you are interested in keeping text-format keyworded for your arch.
~ia64 done
~ppc'd
~ppc64 now; changing to fixed as last arch
