State rebuilt using African oil (10)

I believe the answer is:

california

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

'state' is the definition.
(I know that California is a American state)

'using african oil' is the wordplay.
'using' is an anagram indicator (the letters used in a different way).
'african'+'oil'='africanoil'
'africanoil' anagrammed gives 'CALIFORNIA'.

'rebuilt' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.

Can you help me to learn more?

(Other definitions for california that I've seen before include "The Golden State" , "US state" .)

I've seen this clue in The Irish Times.
