Zypher, you did drop ~alpha ~sparc and ~ia64 from latest libquicktime because they are missing x264-dev, but I cannot find any re-keywording bug, which would mean the arches will be lagging out this way. Filing one now, as a similar problem hit media-video in the past, with libquicktime that time, too, iirc.
~sparc keyword added
Done, thanks.
