TBH I've had limited success with cross-compiling and this was for an x86 guest on amd64 buildhost, but I have not tried aarch64 (yet). > I've built the cross toolchain with 'crossdev --taget > aarch64-unknown-linux-gnu' per wiki [2].

Did you download the correct stage3? There are split-usr and merged-usr tar archives. Since split-usr is or will be soon deprecated you better start with merged-usr. > The crossdev environment on the desktop knows nothing about the packages > installed on the Pi, so I copied /var/db/pkg from Pi to > /usr/aarch64-unknown-linux-gnu/var/db/pkg on the desktop.

make.profile and the stage3 fs are the same on both buildhost and guest. Also diff the two /var/lib/portage/world and don't forget to compare/grep for different USE flags between the two systems. Finally, if nothing works as intended consider compiling in QEMU: https://wiki.gentoo.org/wiki/Embedded_Handbook/General/ Compiling_with_QEMU_user_chroot
