Machu Picchu country (4)
I believe the answer is:
peru
'machu picchu country' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for peru that I've seen before include "South American country" , "Machu Picchu country" , "Lima's country" , "Nazca, Cuzco here" , "Mario Vargas Llosa's country" .)
