I solved your problem. If you delete IOC_LIBCFS_PING_TEST ioctl case  from libcfs/libcfs/module.c it work again. 
That ioctl has not been is use for some time and it can be removed. What is happening is libcfs_nid2str is being
called which requires lnet.ko now. This is a layer violation. I will be sending a patch very shortly.
