with top as (select distinct on (sysname) sysname, snapshot from
build_status_recent_500 where branch = 'HEAD' order by sysname,
snapshot desc ) select * from top where exists (select 1 from
build_status_log l where l.sysname = top.sysname and l.snapshot =
top.snapshot and l.branch = 'HEAD' and l.log_stage = 'config.log'
and l.log_text ~ 'python2\.4');

This returns no rows.

Maybe we need to set up a Centos5 or RHEL 5 animal.
