The error is only about building documentation. Unfortunately, documentation generation is broken quite often. If we were to stop after the error, we'd have to patch all of our kernels to fix the problem (this is a lot of low-priority work), so I don't think there's much sense in aborting the merge here. We tend not to patch vanilla-sources, but this particular problem is fixed in recent gentoo-sources-2.6.11 releases.
Ill agree that killing the merge if docs cant be built is a bad idea, although that being said maybe it would be nicer if we just supress all output for the doc building stage, and wrap it all in an ebegin/eend just to make it more cosmetically pleasing. At least its also more descriptive. Thoughts?
