Newly released package not building on Travis

I recently released a package for the first time and it’s failing on the Travis build farm and i’m having some trouble figuring out why. The Ubuntu 16.04 build can be found here, and the url for the repo i’m releasing can be found here. Focusing on just the Ubunt 16.04 build farm failure for now, I see the following trace in the failed build console,

11:59:25   - catkin

My package rdl_cmake has a build dependency on cppcheck_junit which is a pip package and I have called out that dependency in the package.xml. Also there is a key for cppcheck-junit-pip which is the key i’m using to call out the dependency, and a rosdep key for that is listed here, so i’m not sure where it’s getting tripped up.
