Nevermind what I posted. Found the file in the Makerfarm Upgrades folder. Sliced and it printed well.

By the way, I punted on installing Slic3r 0.9.9 Linux version. The Github procedure wasn't working even when I started from a fresh install. What worked easily was using WINE and the Windows Slic3r 0.9.9 version. Tested by slicing the cube STL that comes with the Pegasus software collection as well as with the relay board upgrade. The only difference is that the infill with the cube that I sliced made for a bit heavier of a print.
