After installing wolverine with kernel-headers and kernel-source, I am 
getting the following error message when I type 'make xconfig'--I am 
printing here only the line of the error message:

    net/ipv4/netfilter/ip_vs/Config.in: 9: incorrect argument

I looked at this file, and indeed the line 9 shows:

    if [ "CONFIG_IP_VS" == "m" ]; then

There is one equal sign too many, it should be:

    if [ "CONFIG_IP_VS" = "m" ]; then

After fixing that, 'make xconfig' works fine.

Cheers,
