[oe] libusb-1.0-0, Required build target 'myrootfs' has no buildable providers.

I'm compiling myrootfs for the beagleboard, and have IMAGE_INSTALL += 
"libusb1" in my recipe. This has worked fine until a recent update, but 
now it fails with the following:

NOTE: Handling BitBake files: | (7156/7156) [100 %]

I deleted my TMPDIR and then it compiled ok, but when I tried to compile 
again, I got the same message. Neither myrootfs.bb nor recipes/libusb 
have been changed since the last time this worked for me, so I suspect 
something else is causing this.

Any ideas?
