Comment (by ryandesign@…):

 pure links with libncurses, therefore it needs the dependency declared. We
 use the list of declared dependencies to find ports that need to have
 their revisions increased to rebuild them after a dependency's library
 version number has been increased. This happened for example when ncurses'
 library version increased from 5 to 6 in 2015; pure was broken until its
 revision was increased in r140525, and to remind us that this needs to
 happen anytime ncurses' library version changes again in the future, I
 also added the ncurses dependency at that time.

 If pure linking with libncurses is unnecessary, and only caused by
 readline, then that would be a bug we should report against readline. I
 agree that ports that link with readline do also link with ncurses, but I
 do not know whether that linkage is unnecessary.
