I'm experimenting with Portable Services, but the "walkthrough" example [1] doesn't seem to work. The error: Failed to execute /usr/bin/portable-walkthrough-go: No such file or directory probably means something fairly fundamental is wrong, but I can't seem to figure out what that might be. Any suggestions?
