[ros-release] build farm not resolving PIP dependencies?

Mike Purvis and I are working on a new roslint package implementation. That
package wants to depend on cpplint, a PIP package defined in rosdep as
python-cpplint:

https://github.com/ros/roslint/issues/6
<http://jenkins.ros.org/job/devel-hydro-roslint/ARCH_PARAM=amd64,UBUNTU_PARAM=precise,label=devel/2/console>

$ rosdep resolve python-cpplint
#pip
cpplint

But, the build farm tries to install it using apt-get, instead:


http://jenkins.ros.org/job/devel-hydro-roslint/ARCH_PARAM=amd64,UBUNTU_PARAM=precise,label=devel/2/console

How can we get Jenkins to load this dependency correctly?

Is this a bug in jenkins_scripts?
