People said to be longing perhaps for some land (5)

I believe the answer is:

acres

I'm a little stuck... Click here to teach me more about this clue!

'some land' is the definition.
(acres measure land)

I don't understand how the remainder of the clue works.

(Other definitions for acres that I've seen before include "Cares about the tracts of land" , "Rival played" , "farmland maybe?" , "fields?" , "Extensive landed property (often rolling)" .)

I've seen this clue in The Globe and Mail.
