May the links have been chamged by GetComponents?) and so they were not linked to the files in 'repos'. Interesting problem.

How did you move the trees around?  Did you use a method which preserves symbolic links?  If you copy a Cactus tree using "cp -r", you will not get the symbolic links.  From the Mac OS cp man page:

You should use "cp -a" which copies symlinks.  If instead you use rsync, be sure to use the -a option, which correctly copies everything.

I don't think these warnings are unrelated.

I suspect that GetComponents is trying to work out whether it needs to stash changes.  Since it then goes on to stash, I assume the answer came back as "yes", even though "git stash" is reporting no changes.  Something is wrong here, maybe because of the symbolic links being corrupted?

This is also bad - the error was "no stash found" because there was nothing to stash in the first place.
