simple join is beating me - Mailing list pgsql-sql

hi folks

i have the following:

select o_ord_date as o_date, count(o_id) as orders   from orders where o_de_id in (5,6) and o_ord_date >
CURRENT_DATE-'1
 
month'::interval   group by o_ord_date
order by o_date desc

and

select o_act_del_date as o_date, count(o_id) as delivery    from orders    where o_de_id in (5,6) and
o_act_del_date> CURRENT_DATE-'1 month'::interval and         o_act_del_date <= CURRENT_DATE   group by o_act_del_date
 
order by o_date desc

These give me
  o_date   | orders
------------+--------2009-07-10 |      42009-07-09 |      52009-07-08 |     122009-07-07 |      52009-07-06 |

and 
  o_date   | delivery

How do i get
  o_date   | orders | delivery
------------+--------+----------2009-07-13 |        |        52009-07-10 |      4 |        32009-07-09 |      5 |
