Bug 191114

Performing a buildworld using 10.Stable on both amd64 and i386 platforms result in the error (below) during stage 5.1. /etc/src.conf contains this line
WITHOUT_NCURSESW=YES
when the line is removed, the build completes successfully. The world is prepared for headless servers, so unnecessary material is removed.
