[DRE-maint] Bug#675951: ruby-ncurses: FTBFS: -Werror=format-security

[Steven Chamberlain]

Package: src:ruby-ncurses
Version: 1.3.1-1
Severity: serious
Tags: sid wheezy
X-Debbugs-Cc: debian-ruby at lists.debian.org
Justification: fails to build from source (but built successfully in the
past)

Hi,

Built against libruby1.9.1 1.9.3.194-1, ruby-ncurses now FTBFS due to
failing a build-hardening check:
