I found the issue. You must substitute the instances of the string
"ncursew5-config" with "ncursesw6-config" before running autogen.sh.
This is because we only package version 6 of the ncurses library. By
making this change, I was able to build angband reproducibly. Should we
enable the SDL, X11 and GTK+ interfaces as well?
