Not really keen to see vagrant (5)
I believe the answer is:
nomad
'vagrant' is the definition.
(thesaurus)
'not really keen' is the wordplay.
'not really' becomes 'no'.
'keen' becomes 'mad' (both can mean enthusiastic about).
'no'+'mad'='NOMAD'
'to see' is the link.
(Other definitions for nomad that I've seen before include "Roving person" , "Itinerant" , "Unsettled character" , "someone who can't settle" , "Member of a wandering pastoral community" .)
