Description of problem:
I downloaded the master branch of the github.com repository (version 2.2). The I have downloaded all of the dependencies via yum-builddep und changed the dir into backend. If I simply run "tito build --test --rpm" there is no success. There is no way to create the spacewalk-backend.rpm on the make process. Everytime there comes this output:

"
