when I use emerge -s as non-root, I get the following warning:
$ emerge -s evince
!!! Directory initialization failed: '/var/lib/portage'
!!! chown('/var/lib/portage', -1, 1000)
!!! Directory initialization failed: '/var/cache/edb'
!!! chown('/var/cache/edb', -1, 1000)

It doesn't seem to affect operation of the code otherwise.
It is probably something I did but I don't know what. It started after I used emerge as root from the console. My user account has always been in the wheel group and I added my account to the portage group after this started to happen. Exception still there.
Is there a way to fix it?
