When updating from bind 9.14.7 to 9.14.8, emerge shows preserved libraries *in bind itself* after it finishes. Emerging bind again (e.g. by running emerge @preserved-rebuild) clears these up. I would speculate that maybe the new bind is being built against libs from the currently-installed bind rather than against the new libs that have been built with the package. Installing bind on a system that doesn't currently have it works fine so it's obviously got the new libs in the linker search path, but they must have a lower priority than the ones in /usr/lib64. Whether this is actually a Gentoo thing or a hidden problem with upstream's build system that is being detected by Portage I cannot say. Alternatively, perhaps Portage itself is getting confused by something about the way bind is linked and returning false preserved libs...? Reproducible: Always Steps to Reproduce: 1. emerge =net-dns/bind-9.14.7 (I used a copy pulled into a local overlay) 2. emerge =net-dns/bind-9.14.8 Actual Results: Emerge finishes with: !!! existing preserved libs: >>> package: net-dns/bind-9.14.8 * - /usr/lib64/libdns.so.1310 * - /usr/lib64/libdns.so.1310.0.2 * used by /usr/lib64/libisccfg.so.1302.0.3 (net-dns/bind-9.14.8) * - /usr/lib64/libisc.so.1309 * - /usr/lib64/libisc.so.1309.0.2 * used by /usr/lib64/libdns.so.1311.0.0 (net-dns/bind-9.14.8) * used by /usr/lib64/libisccc.so.1302.0.0 (net-dns/bind-9.14.8) * used by /usr/lib64/libns.so.1307.1.0 (net-dns/bind-9.14.8) Use emerge @preserved-rebuild to rebuild packages using these libraries * After world updates, it is important to remove obsolete packages with * emerge --depclean. Refer to `man emerge` for more information. Expected Results: No preserved libs. My USE flags for bind: net-dns/bind-9.14.8::gentoo USE="caps zlib -berkdb -dlz -dnsrps -dnstap -doc -fixed-rrset -geoip -geoip2 -gssapi -json -ldap -libressl -lmdb -mysql -odbc -postgres -python (-selinux) -static-libs -urandom -xml" PYTHON_TARGETS="python2_7 python3_6 -python3_5 -python3_7" Emerge info below is from my desktop system on which I've just reproduced the issue for this bug report; it was initially observed on a server elsewhere. I have a feeling I may have seen the issue before but was too busy to stop and look into it properly so I just ran emerge @preserved-rebuild and it went away. # emerge --info Portage 2.3.79 (python

Same here.
Tested with 9.16.1 - in src_configure() before econf: for i in "${S}"/lib/*; do [[ -d "$i" ]] && append-ldflags -L"${i}"/.libs done

Should not be a problem in newer versions.
