Nothing really; you just need a kernel built with the "nfs" filesystem
or you can dynamically load the "nfs" module.
The portmap, mountd, and nfsd are really only needed on the server.

I think this means the server isn't set up right. Are you sure
the server is "fine"? Is it running mountd (rpc.mountd)?
Use "rpcinfo -p server_name" from the client to see what is
registered on the server. Also check the system log file on the server.
