password auth woes on sparc64/FreeBSD

It seems to me that auth on the local interface(?) is broken somehow on
sparc64.

[data/pg_hba.conf]
local postgres,template1 all trust

local postgres,template1 all md5
host postgres,template1 all 0.0.0.0/0 md5
host postgres,template1 all ::/0 md5
[--]

Well, what I really want to do is to remove the trust line from config.
But that way i need a .pgpass file so the server can start/control
itself without asking me for password. And if i want .pgpass file i need
some auth.

[session transcript/same machine]
> psql -U pgsql postgres
Welcome to psql 8.2.4, the PostgreSQL interactive terminal.

\? for help with psql commands
\g or terminate with semicolon to execute query
\q to quit

postgres=# alter role pgsql password 'somepass';
ALTER ROLE
postgres=# \q
> psql -h localhost -U pgsql postgres
Password for user pgsql:
psql: FATAL: password authentication failed for user "pgsql"
[--]

It fails for any user and any password.

[session transcript/other machine]
> psql -h blade -U pgsql postgres
Password for user pgsql:

But I can log from another machine flawlessly...

PS: Can assist in debugging if someone would point me what and how.
