ospf over frame....stumped

Ok, I am almost embarrased to ask this one, but I can't figure out what is
happening and I know I did this before. Arg! R5 is connected to a frame
relay with 3 routers (r2, r4 and r6). R5 is to be the DR. I have everything
set up as non-broadcast (priorities accordingly) and for some reason, I cannot
get the neighbors to come up (except one....see the output of show ip ospf
neighbor at the end). Any ideas?
