Comment (by ryandesign):

 According to
 https://groups.google.com/g/linux.debian.bugs.dist/c/lBayEfISTCY this is
 because of a change in ncurses that makes that structure opaque. An
 accessor function must now be used. It's not a MacPorts-specific problem
 so if upstream still exists, report it to them or see if they already have
 a fix. If not, see if another distribution already has a fix.
