[vserver] newbie question: /usr/sbin/vserver-info: No such file or directory

Hi
      I am running debian etch, and after install new vs, try to run is, got:

/usr/lib/util-vserver# vserver asterisk1 start
/usr/lib/util-vserver/functions: line 500: /usr/sbin/vserver-info: No
such file or directory
/usr/lib/util-vserver/vserver.functions: line 685: /usr/bin/find: No
such file or directory
/usr/lib/util-vserver/vserver.functions: line 686: xargs: command not found

Failed to start vserver 'asterisk1'

        But I have vserver-info, find, xargs on the host system

mailsrv:/usr/lib/util-vserver# which vserver-info
/usr/sbin/vserver-info
mailsrv:/usr/lib/util-vserver# which find
/usr/bin/find
mailsrv:/usr/lib/util-vserver# which xargs
/usr/bin/xargs
mailsrv:/usr/lib/util-vserver#

anything could be wrong?

/usr/lib/util-vserver# vserver-info
