I found one problem that is quite similar to your problem on our DEC Alpha.
And when I checked /etc/services, I found that port 5001, which P4 used
for startup remote processes, had already been used.  To solve this problem,
just change a constant for UNRESERVED_PORT in include/p4_sock_util.h.

Hope this helps,
Natawut.
