The reason for the validator to protest here is that pkg-config has a
bug that will remove one of the -Wl,-framework flags in its output. See
the discussion on fink-Bugs-978293.
What libusb should do (and the libusb.info file contains traces of an
older effort to do so) is to replace
-Wl,-framework -Wl,IOKit -Wl,-framework -Wl,CoreFoundation
by what is equivalent for the linker:
-Wl,-framework,IOKit -Wl,-framework,CoreFoundation

Read man gcc.

That would be worse. In addition to pkg-config eating one of the
-framework flags, libtool would probably create another disaster by
ordering these four words alphabetically...

Yes. I put a new revision libusb-0.1.12-1011 into 10.4/unstable that is
supposed to fix this. Please try.
