packagekit-action-lookup is acturally a extension module of polkit, but there is no clear link against polkit-backend. This problem will cause undefined references when building with LDFLAGS="-Wl,--no-undefined". And, maybe runtime error if libpolkit-backend-1.so.0 is not there.
The patch given at @URL fixes this problem.

I think this is the proper fix -- could you please retry your build and report success / failure please? Thanks.
But where does POLKIT_BACKEND_1_LIBS come?
