bind 9.5.1b1(rndc.key) Problem

[iman]

Dear Admins
I compiled bind 9.5.1b1 and installed it on solaris9.
here are my compile options:
./configure --enable-shared=no --sysconfdir=/opt/namesurfer/config
--sbindir=/opt/namesurfer/named --localstatedir=/opt/namesurfer
--prefix=/opt/namesurfer
but when i started named ,i saw that it got error with:
-sh-3.2# Aug 21 21:32:00 lct-test named[23355]: [ID 873579
daemon.notice]
starting BIND 9.5.1b1
Aug 21 21:32:00 lct-test named[23355]: [ID 873579 daemon.error]
/opt/namesurfer/config/named.conf:14: unknown key 'rndckey'
Aug 21 21:32:00 lct-test named[23355]: [ID 873579 daemon.crit]
loading
configuration: failure
Aug 21 21:32:00 lct-test named[23355]: [ID 873579 daemon.crit] exiting
(due
to fatal error)
however i put rndc.key in /opt/namesurfer/config!
but when i delet this part of named.conf:
inet  127.0.0.1 port 953 allow { 127.0.0.1; } keys { "rndckey";};---
>inet 127.0.0.1 port 953 allow { 127.0.0.1; };
the named start properly!
how can i fix this problem without deleting "keys { "rndckey"; }"
from  named.conf?
should i change my ./configure options for this or change some other
things after compile?
why bind get this error from named.conf?
any idea would be appreciated
