nfssvc not available or version mismatch (nfsv4 client)

Hi all,

I am trying to run NFSv4 client on 64bit FreeBSD 9.0-Current.

I have inserted into /etc/rc.conf following lines:
nfsuserd_enable="YES"
nfscbd_enable="YES"

and after restart, during boot there is a meesage:

Jan  6 23:50:56 vm-salwerom root: /etc/rc: WARNING: failed to start nfsuserd
Jan  6 23:50:56 vm-salwerom kernel: KLD nfscommon.ko: depends on nfssvc - 
not available or version mismatch
Jan  6 23:50:56 vm-salwerom kernel: linker_load_file: Unsupported file type
Jan  6 23:50:59 vm-salwerom root: /etc/rc: WARNING: failed to start nfscbd
Jan  6 23:50:59 vm-salwerom kernel: KLD nfscl.ko: depends on nfssvc - not 
available or version mismatch
Jan  6 23:50:59 vm-salwerom kernel: linker_load_file: Unsupported file type

the file nfssvc exists:
vm-salwerom% ls /boot/kernel/nfss*
/boot/kernel/nfsserver.ko       /boot/kernel/nfssvc.ko

Is there a problem with kernel modules or something else?
