Can't start postmaster on -HEAD

This is a fresh snapshot -- is also happened on Nov 28th snapshot, too:

-bash-3.2$ pg_ctl start
server starting
-bash-3.2$ LOG:  authentication option not in name=value format: sameuser

CONTEXT:  line 70 of configuration file "/var/lib/pgsql/data/pg_hba.conf"
FATAL:  could not load pg_hba.conf

Line 70 is:

local   all         all                               ident sameuser

(Ran initdb via RPM init script btw).

Am I missing something?
