Poet eschewing university calls for port (4)
I believe the answer is:
aden
'port' is the definition.
(port in Yemen)
'poet eschewing university' is the wordplay.
'poet' becomes 'Auden' (WH Auden, 1907-1973).
'eschewing' is a deletion indicator.
'university' becomes 'U' (abbreviation for university).
'auden' with 'u' taken away is 'ADEN'.
'calls for' is the link.
(Other definitions for aden that I've seen before include "Dean out in the seaport city" , "Dean is in the Yemen, strangely" , "Dean is out in the Middle Eastern port" , "Port city of Yemen" , "somewhere on the Arabian peninsula" .)
