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

'for a libertine' is the definition.
(rake is a kind of libertine)

I can't explain the rest of the clue.

(Other definitions for rake that I've seen before include "set at an angle" , "Inclination - dissolute man" , "Collecting implement - ladies' man" , "Garden tool with teeth" , "Leaves collector" .)

I've seen this clue in the Evening Standard.
