Alexander, it would seem that find /usr/local/*bin* /usr/local/lib* -type f \ | xargs ldd -f '%p|%A\n' 2>/dev/null \ | grep '^not found' | cut -d '|' -f2 \ | xargs pkg which -q | sort -u is prone to false positives, since ldd is sensitive to LD_LIBRARY_PATH, viz.: $ find /usr/local/*bin* /usr/local/lib* -type f \ | xargs ldd -f '%p|%A\n' 2>/dev/null \ | grep '^not found' | cut -d '|' -f2 \ | xargs pkg which -q | sort -u firefox-84.0_2,2 $ export LD_LIBRARY_PATH=/usr/local/lib/firefox $ find /usr/local/*bin* /usr/local/lib* -type f \ | xargs ldd -f '%p|%A\n' 2>/dev/null \ | grep '^not found' | cut -d '|' -f2 \ | xargs pkg which -q | sort -u $ So make sure you look into what exact library is missing and if it's actually somewhere "non-standard", that directory should be in LD_LIBRARY_PATH.
