I don't remember exactly what happened at the time, I was distracted by something else, it didn't complete but whether it gave a panic or froze and I reset the VM -I am not sure. Today I tried 'pkgclean', which failed. It turned out that in the python313 work directory there was a subdirectory, result of a test, which I was not able to remove - any attempt to access it results in 'Operation not permitted'. I was able to move its parent directory to / and then complete the 'pkgclean', but I am left with this weird empty directory, to which I am able to 'cd', but not do anything. The directory name looks like:

My first thought would be that one of the extended file flags is set.
Do a "ls -lo" and consult 'man chflags' to see if schg or uchg got set
somehow.
