You might try to set up a simple web server like thttpd or simpler on
port 5432 and that way you can troubleshoot opening the socket listener
is a more simple environment with possibly some different error
messages. Also you can run a simple perl/python/ruby/java script (like
this http://myclass.missouri.edu/~atb6x2/NETSERV/NS_serverpl.html) to
(try to) open a socket listener on 5432 and have it just sit there.

If you do that the output from strace would be shorter than trying to
start up pg and you might get an idea where the socket problem is.
