Interesting. When I had replied in the past that I was unable to reproduce this, I had been building with a local patch that set macosx-version-min to 10.7 for everything. When I read this I tried building again without that patch and sure enough, red blob. When I rebuilt with version-min set to 10.7 it went away again.
