Description of problem:
I applied the latest updates to one of my FC6 systems yesterday and now I cannot
mount anything.  After some experimenting, I found the mount command claims
NFSv3 is not supported:
   # mount -t nfs -o proto=tcp,vers=3 server:/some/dir /mnt
   NFS version 3 is not supported.
   #

However, going directly to mount.nfs works fine:
   # mount.nfs server:/some/dir /mnt -t 3 -o proto=tcp,vers=3
   # 

My other FC6 system still has nfs-utils-1.0.9-8.fc6 and everything works fine on it.


Version-Release number of selected component (if applicable):
nfs-utils-1.0.10-1.fc6

How reproducible:
Every time

Steps to Reproduce:
1. Try to mount with options proto=tcp,vers=3
2. Note error message
3. Try to mount with mount.nfs command and it works
  
Actual results:
mount fails with an error message claiming NFS version 3 is not supported

Expected results:
The mount should work
