I solved this by runing catkin_make install to install it into a directory instead of using the devel dir, and then source install_dir/bash.setup. If you read the /kobuki_node/plugins/nodelet_plugins.xml file, it specifieslib/libkobuki_nodelet in the library path attribute, which cannot be found in devel dir, but is indeed present after catkin_make install.
