You dropped ppapi_cpp.  Did you mean to drop ppapi (which requires waiting for a
DEPS update to get your library_deps.py change)?

BTW, your library_deps.py change is fine while PPAPI-related stuff remains on
the NaCl side, but eventually we want to drop PPAPI-related stuff from the NaCl
side...  So I'd leave both "ppapi" and "ppapi_cpp" in here.

Yes, this was a textual error.
Amusingly this one isn't even hooked into the build, so nothing broke.
