Read the comments in tcp.h near the offending error. You just need to add
an appropriate clause for whatever your favourite HZ value is. I had to do
this for tbox too; HZ is fixed to 1000 there by the hardware and I couldn't
change it even if I wanted to.
Incidentally, HZ=64 is probably a bit on the low side. I'd set it to 128 or
maybe even higher - the overhead from timer interrupts is really not as bad as
you might think.
