Region containing Peru has Inca material all over the place (5,7)

I believe the answer is:

latin america

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

'region' is the definition.
(I know that Latin America is a region)

'inca material all over the place' is the wordplay.
'all over the place' indicates an anagram.
'inca'+'material'='incamaterial'
'incamaterial' anagrammed gives 'LATIN AMERICA'.

'containing peru has' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.

Can you help me to learn more?

(Other definitions for latin america that I've seen before include "Non-English-speaking New World" , "Spanish- and Portuguese-speaking region" , "Western territories" , "Spanish-speaking area" , "Romance language-speaking countries south of US" .)

I've seen this clue in The Times.
