postmaster startup failure

WHen running PostgreSQL 7.3.3-1 (from rpm's) on Redhat 9.0 I got the
following in logs and the postmaster will not start up.

Any Ideas what I could do to start up ?

This in on a laptop used for development, but I still would like to not
initdb.

postmaster successfully started
