Order by clause in 'select distinct'?

When I create a view by a query like the follow query:

SELECT DISTINCT ON (o.ordergenkey) o.ordergenkey, lip.payment FROM Ordr o,
LineItemPayment lip
WHERE o.ordergenkey = lip.orderfkey
and o.ordergenkey = ?

The view is created with an ORDER BY clause on the o.ordergenkey...

I think it might be an enforce rule for createing a view with a DISTINCT ON
phrase.

I would like to, if possible, get rid of the ORDER BY clause as it slow the
query to
a crawl.

Any ideas?
