I had thought "unimplemented" was part of 3.4.x, but checking the sources, I 
see it is not.

It still looks to me as if your path is not what it should be. My guess is that 
you're still using the path for 3.4.

Try "./run-octave", type "path", and then "quit". Is the path correct ?

Assuming it is not, try "./run-octave --no-init-file", and then type "path". Is 
the path the same ?

Also if "mean (1:10)" is still returning same error, you can type ...

        which mean

... to see what mean.m is being called.
