This breaks all the Howtos and Wiki about GPG encrypted LUKS key.
Already fixed in the v3.5.2.0 release, which bumps the gnupg version. Please test & confirm.

Unfortunately I have this problem with sys-kernel/genkernel-3.4.52.4 (which uses app-crypt/gnupg-1.4.11), so I'm guessing the issue re-occured. On the forum (https://forums.gentoo.org/viewtopic-p-8112528.html#8112528), someone mentioned to bump the GnuPG version to 1.4.21 and this did work for me.

With sys-kernel/genkernel-3.5.2.0 and app-crypt/gnupg-2.2.0, the option GPG="yes" is able to build an initramfs successfully. I did no further gpg testing yet..
