Have you tried just installing it from source? The package is available for indigo.

2014-03-14 04:43:23 -0500 asked a question Exporting Linear Actuators to an URDF from SolidWorks

I would like to try running a CNC mill using ROS. More specifically I want to use RVIZ to help us visualize a CNC task prior to running it live on the CNC. My understanding is that one of the first step in this process is exporting my robot URDF using the SolidWorks URDF exporter. The exporter seems geared towards exporting revolute joints but doesn't seem to have any functionality to setup linear actuators / prismatic joints. Is this possible? If so what are the steps for specifying a linear actuator? If someone can point me the way I would love to write a tutorial about this.

Here are a couple of example 3 axis gantries that use linear actuators similar to the one I am working with:
