ceph-deploy should handle better this specific problem, you've hit the
issue where $PATH is not enabled for a certain user over ssh, so it
will not be able to execute commands because it can't find the
executables.
A temporary workaround is to set the $PATH for all users explicitly
until we fix this issue (I opened: http://tracker.ceph.com/issues/6428
to track this).

Ah good find, somehow this error went pass our checks, I just opened an issue to
fix this asap: http://tracker.ceph.com/issues/6427
