Something extremely bizarre has happened; it appears that the TCP
dissector's "register" routine wasn't called, as there's no "tcp.port"
dissector table.
I would suggest doing
make distclean
in the top-level directory, removing the "register.c" file if it wasn't
removed by the "make distclean", re-running the configure script, and
re-doing a build.
