ROSARIA Tutorial Groovy catkin_make issue

edit

I've been running through this tutorial for a few days, i'm now seeing a few mistakes I made [not installing the Aria-2.7.2 file and Mobilesim-0.5.0 (as I'm not attached to a robot at the moment)] but I've done all that now(the ROSARIA tutorial should probably point out that you should do that ahead of time but I suppose I just skipped that step). Now when I've made my workspace and I use the catkin_make command in the ~/catkin_ws directory everything runs fine until I get to

    [ 83%] Built target ROSARIA_gencfg

and now I don't know what I can do to fix it. Can anyone help?
