Tribe's difficulty dividing African country (8)
I believe the answer is:
benjamin
'tribe's' is the definition.
(I've seen this before)
'difficulty dividing african country' is the wordplay.
'difficulty' becomes 'jam' (jam can mean a tricky situation).
'dividing' is an insertion indicator (inserted letters divide the word).
'african country' becomes 'benin' (country in Africa).
'jam' put within 'benin' is 'BENJAMIN'.
(Other definitions for benjamin that I've seen before include "tribal leader" , "Gum resin" , "Netanyahu or Franklin" , "Jacob's youngest son" , "Boy" .)
