bind 9.10..0-P1 rndc: 'retransfer' failed: not found; other rndc commands are ok

[grantksupport at operamail.com]

I have bind 9.10.0-P1 installed, and running in a chroot.

which named
	/usr/local/bind9/sbin/named
which rndc
	/usr/local/bind9/sbin/rndc

named -v
	BIND 9.10.0-P1

ps ax | grep named
	7110 ?        Ssl    0:18 /usr/local/bind9/sbin/named -t
	/var/chroot/named -n 4 -S 1024 -u named -c /etc/named.conf -d 90

/usr/local/bind9/sbin/named-checkconf -t /var/chroot/named

All lookups are working.  Transfers to slaves work as expected when I
increment zone serials and restart the server.  But when I try to
initiate a retransfer using rndc, the 'retransfer' command isn't found:

I've looked around online, and 'retransfer' seems to still be a valid
command.

What's wrong with my usage of retransfer?
