I've had a long-standing problem with using source code cloned from github. I can do a git clone, and get it to build, but later I can't ever refresh the source code. If I do a "git pull" even many months later it just tells me that the files are up to date and it doesn't do anything.
Maybe I need to make some edit to "rakudo/.git/config", but I don't see what it would be...
