Hi Last package using librrd4 is collectd. It should no longer FTBFS on most archs (bug #822397 was fixed in linux headers earlier this week). The binnmu should be given back. https://ftp-master.debian.org/cruft-report-daily.txt https://release.debian.org/transitions/html/auto-rrdtool.html https://buildd.debian.org/status/package.php?p=collectd
