Libra upset with last letter from country (6)
I believe the answer is:
brazil
'country' is the definition.
(Brazil is an example)
'libra upset with last letter' is the wordplay.
'upset with' indicates an anagram.
'last letter' becomes 'z' (last letter of the alphabet).
'libra' mixed up with 'z' gives 'BRAZIL'.
'from' is the link.
(Other definitions for brazil that I've seen before include "Football World Cup holders" , "Red wood; nut; country" , "Rio's country" , "Largest South American country" , "Amazon's country" .)
