Hmm.  That sounds pretty broken.  Does anything get logged in the
postmaster's log file (wherever you redirected its stdout/stderr to)?
Does a core file get created?  (Look for a core file both in the
postgres data directory and in its subdirectories.)  If there is a
core file, extracting a backtrace from it with gdb or your favorite
debugger would help us figure out what's wrong.

My first guess is some sort of configure/build foulup.  What kind of
system are you running on?  Which template did 'configure' pick?
