I have a fresh installed Funtoo on my laptop, and I am trying to install GNOME desktop for it. However, when portage comes to compile app-crypt/gcr-3.6.2, it failed. I searched the Internet and found this is an already known issue by Ubuntu: https://bugs.launchpad.net/ubuntu/+source/gcr/+bug/1163786. However, this patch is not applied to Funtoo portage, I think that's why this happens.

I attach some necessary info below:
