I get a weird error when executing the following ipset command:

[root@test1 ~]# ipset -N test hash:net,port
ipset v6.4: Kernel supports hash:net,port type, family INET with maximal 
revision 0 while ipset program with minimal revision 1.
You need to upgrade your kernel.

The "revision", as far as I know, is exactly the same - ipset 6.4! The 
userspace has been compiled from the released v6.4, while the kernel 
part was built from a snapshot dated 24 April, which included the 3 
patches not present in .39-rc4 (so, in essence, if anything, the kernel 
part should be newer than the userspace part of the released v6.4, 
right?). It is strange that I do not get this error when attempting any 
other type of set (hash:ip or hash:net).

It is also worth noting that I have IPv6 administratively disabled on 
that machine, though do not know if that's the reason for the above 
error. How can I correct this?
