Aragorn, Gollums equal?

[lathspell]

he captured him indeed, but that was at unawares. Gollum was starving at the time and lurking in a pool for fish and what not.
When Frodo is keeping watch on Anduin's banks and sees Gollum Aragorn wakes suddenly and asks what is the matter for he sees Frodo with drawn sword. Frodo says: 'Gollum!'
Aragorn's answer is something like this: 'Ah! So you now about him. Yes, he is following us since moria, I hoped that on the river we would lose him, but he is too cunning a swimmer. I tried to capture him once or twice but he gave me the slip every time.
