I've noticed that trying to build any git-r3 github ebuilds results in

Couldn't resolve host 'github.com'

, despite me being able to git clone them manually.

I've attached the output of sudo ebuild --debug /var/git/meta-repo/kits/core-kit/sys-fs/udev/udev-9999.ebuild unpack as an example, as well as emerge --info.
