I have installed brew and gource and I have uninstalled and re installed but when I run it it crashes with gource stopped unexpectedly. I know this is meant to install and run out the box as I have seen it work with windows machines.
I get Segmentation fault: 11 as the error.
Although it didn't help for me, perhaps the solution described in this ticket could solve it for you:
Had the same problem and found this issue in the repo: segmentation fault (home-brew).
After running brew update && brew upgrade, gource ran as expected.
brew update && brew upgrade
