"num_slots" is an old pf_ring parameter, now replaced with "min_num_slots"
Please try with:
$ cd PF_RING/kernel
$ make clean
$ make
$ sudo make install
passing "min_num_slots" instead of "num_slots"

Your kernel version should work. Anyway, perhaps it's time for an upgrade :-)
Usually we compile the code on Ubuntu, Gentoo, and some other distributions
