I've written a diagnostic thingie that dumps the state of the tcp sessions
and am testing it before sending it out for the stream3 users to try out.
In so doing, I've run into two problems.  First, the spo_database problem
is still there; it can't find PQsetdbLogin.  Second, I get this:

Program received signal SIGSEGV, Segmentation fault.

spp_portscan doesn't pertain to what I'm doing, so I'll just comment it
out of the conf, but I thought that I would report this anyway.  If anyone
wants more info, I'm happy to provide it.
