A member of the people who built Machu Picchu (4)

I believe the answer is:

inca

(Other definitions for inca that I've seen before include "An old Peruvian like Cain" , "Member of old South American Indian people of Peru" , "member of historic race" , "Ancient Andean Indian" , "Pyramid builders" .)

I've seen this clue in The Times and The Sunday Times.
