Hi Zac, this bug is easy to reproduce. I'm seeing it in stable portage, and others are seeing it in ~arch. emerge net-p2p/syncthing. Once you do this, you will see that portage wants to rebuild dev-lang/go-1.14.7 every time you update world. Syncthing will not build with go 1.15, so it needs go 1.14, but go 1.14 should not be rebuilding for every world update. $ emerge --info Portage 2.3.103 (python 3.7.8-final-0, default/linux/amd64/17.1, gcc-9.3.0, glibc-2.31-r6, 5.4.60 x86_64) ================================================================= System uname:
