Hello, Looking at the log[1] at reproducible builds, it looks like a test failure:
> Support for older libltdl interfaces. > > 102: Makefile.inc FAILED > (old-ltdl-iface.at:134) I had a look at Fedora's libtool repository, and there's an interesting commit: "ftbfs: caused by automake 1.16.1"[2]. It might be the same issue that we're seeing, because that commit patches the file tests/old-ltdl-iface.at, and the first build failure at RB[3] happened in 2018-08-13 in buster, while automake 1.16.1 had migrated to buster in 2018-08-10[4]. With best regards, Juhani [1] https://tests.reproducible-builds.org/debian/rbuild/unstable/amd64/libtool_2.4.6-2.1.rbuild.log.gz [2] https://src.fedoraproject.org/rpms/libtool/c/20511dec725523a30496f1183322f8c6658acfdd [3] https://tests.reproducible-builds.org/debian/history/libtool.html [4] https://tracker.debian.org/pkg/automake-1.16
