I have to admit I've read a "steampunk African" story, even if not exactly steampunk. (I wish I could remember the author and title - it was in the 1980s.) It took place in a future world where advanced civilization had moved from America/Europe to Africa, and the narrator was a West African (maybe Nigerian) whose specialty was "Africanizing" the plays of Shakespeare, adapting them to the cultural norms of West Africa. (Though apparently not translating them - the language of his part of Africa was a slightly Africanized English.) If you happen to be interested, I'll be happy to research this some more and see if I can track down the story.
