solaris 10 nfs client broken?

 [root@crapsun ~]# rpcinfo -u localhost nfs  
  
 instead of this:
 
 program 100003 version 2 ready and waiting
 program 100003 version 3 ready and waiting
 program 100003 version 4 ready and waiting

 i get errors.
 
 rpc is having a really bad day. no rpcinfo on the localhost means no mounting of nfs exports from other servers.
 rpc happens to be a good friend of nfs/client:default 
   
 so.  
   
 [root@crapsun ~]# svcs -xv  
 svc:/network/nfs/client:default  
   
 i n t e r e s t i n g  
   
 [root@crapsun ~]# svcs -xv
