Why would Kreversi want a spell checker?

[Dave Horsfall]

MacBook Pro 13", mid 2010; High Sierra 10.13.6.

Kreversi is an implementation of the board game "reversi", but it fails 
with:

    # port install kreversi
    --->  Computing dependencies for kreversi
    Error: Can't install aspell because conflicting ports are active: ispell
    Error: Follow https://guide.macports.org/#project.tickets if you believe there is a bug.
    Error: Processing of port kreversi failed

No error log that I can see, but why on earth would a spell checker be 
required for a simple board game?  Is it because of KDE (ugh!) itself?
