Unknown meta command: fibers

[linas]

The documentation mentions 2.6 REPL Commands -- REPL Command: fibers [sched] but when I run it I get

scheme@(run)> ,fibers
Unknown meta command: fibers

FYI, I also have this:

scheme@(run)> ,scheds                    
No schedulers.

But that is OK, as expected because the scheduler has finished.

FYI, This is built from git clone of today's git repo.
