The make-ncurses-package procedure seems reasonable to be, as it will
also probably ease the upgrade of the package to future major revisions.

However, the introduction of ncurses-5 and ncurses/tinfo-5 has to match
a precise need for a package that is or will be part of Guix. Is that
the case?

Thanks,
