[Nilesh Patra]

Package: libident
Version: 0.22-3.1
Severity: normal
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: timestamps, buildpath
X-Debbugs-Cc: nilesh at debian.org, nilesh at debian.org, reproducible-bugs at lists.alioth.debian.org


Dear Maintainer,

libident fails to build reproducibly because:

a) It injects timestamps in gzip

Please consider applying the attached patch
