[Nobuhiro Iwamatsu]

Source: ruby-ffi
Version: 1.0.9debian-1
Severity: serious
Justification: fails to build from source
Tags: patch

Hi,

ruby-ffi FTBFS on some architecture.
  https://buildd.debian.org/status/package.php?p=ruby-ffi
  http://buildd.debian-ports.org/status/package.php?p=ruby-ffi

Because option of "-m32" and  "-m64"  is architecture specific.
