Jail error ln operation not permitted

[Casper]

Hi,

I have setup 2 jails in FreeBSD 5.4
when they start, abouth have some error for /dev/log...
like that:
#jail /jail/mail/ mail 127.0.0.2 /bin/sh /etc/rc
Loading configuration files.
mail
Setting hostname: mail.
ln: /dev/log: Operation not permitted
Starting syslogd.
...

Abouth jails seems to work ok, but I can`t debug them from logs or 
somewhere, where is problem... what is that?

tnx,
Casper
