Usually, it's:
mount -t devfs devfs /somepath/dev
                  ^^

However, I don't know if that token distinction matters or that it's just a

This can be a problem, if you jexec into the jail as no full environment is 
created, but it's usually just the /dev/tty that is the problem, not std{out|
err|null}.

Have you considered compiling on the host and using DESTDIR on installworld?
