Source: jack-rack
Version: 1.4.8~rc1-1
Severity: serious
Tags: jessie sid
User: debian-qa at lists.debian.org
Usertags: qa-ftbfs-20130620 qa-ftbfs
Justification: FTBFS on amd64

Hi,

During a rebuild of all packages in sid, your package failed to build on
amd64.

Maybe you need to add explicitly the offending lib to LD flags.
