FBSD5.3R:cannot nfs mount when use sharity-light

[Neil]

Hi,
     yesterday i installed FreeBSD 5.3R and installed sharity-light from port.

but i got problem:

#shlight //mypc/share/  /root/win -U user1
Password:
Using port 52751 for NFS.
nfs mount /root/win: [2] No such file or directory

under Freebsd 5.2.1R,sharity-light works good! 

Any advice? 

:)
