Please remember to use WikiFormatting and to fill in the Port field and to Cc the maintainer of that port.

This is a duplicate of #29223, which is a MacPorts base problem which will be fixed in a future version of MacPorts. For now, the solution is to "sudo port clean ncurses" and try again. Cleaning and trying again is the first thing you should try anytime any port fails to install.

and uninstall ncursesw before I could get any further.
