On some systems, these network-related functions are not in the regular
C library, but in other libraries.  Likely you need to add "-lsocket"
or something like that to the link command.

The Postgres configure script presumably got it right, if you were able
to install a working psql.  Try looking at what the makefile for psql
is doing.
