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

'butter no good sent out' is the definition.
I can't tell whether this definition defines the answer.

'from blighty' is the wordplay.
'from' becomes 'e' (I've seen this in other clues).
'blighty' becomes 'land' (I can't justify this - if you can you should believe this answer much more).
'e'+'land'='ELAND'

Can you help me to learn more?

(Other definitions for eland that I've seen before include "Large spiral-horned African antelope" , "One browses in the African plain" , "Antelope seen by Africans" , "Wild beast" , "wild creature" .)

I've seen this clue in The Independent.
