sys-libs/libunwind is actually not multi-slotted, so ${SLOT%/*} should be "0", not "7". Version in soname of main library was changed from "7" to "8" in this commit: https://git.savannah.gnu.org/gitweb/?p=libunwind.git;a=commitdiff;h=ac0acd06f319832eecb60936621b3f98363223a7 This commit was released in sys-libs/libunwind-1.0.1. This means that: <sys-libs/libunwind-1.0.1 should have SLOT="0/7" >=sys-libs/libunwind-1.0.1 should have SLOT="0/8" Currently all ebuilds delete *.la files only with USE="-static-libs". However *.pc files are created and installed since this commit: https://git.savannah.gnu.org/gitweb/?p=libunwind.git;a=commitdiff;h=ea5e90fd9f6ef9840c71b8c4a304793547263de3 This commit was released in sys-libs/libunwind-1.1. *.pc files are a better replacement for *.la files, so I suggest to drop *.la files even with USE="static-libs".

While it would be nice to cleanup SLOT=7->0 it's a purely cosmetic change. Today a lot of packages use SLOT=7 already or don't specify slot at all: [1].

In this output, ":7" is seen to be hardcoded in 4 packages, so not too bad. I volunteer to do the work on updating ebuilds of these 4 packages :) .
