I test it under hardened environment and it needs pkg-config to be manually emerged since currently e2fsprogs ebuild does not show its dependency on pkg-config. If no pkg-config is available, emerge e2fsprogs failed.

I am not sure whether it occurs only under hardened so I post it to Application.
I can confirm that it occurs with the base system. This is due to migration of libblkid to util-linux-ng.
fixed in cvs, thanks http://sources.gentoo.org/sys-libs/e2fsprogs-libs/e2fsprogs-libs-1.41.3-r1.ebuild?r1=1.2&r2=1.3 http://sources.gentoo.org/sys-libs/e2fsprogs-libs/e2fsprogs-libs-1.41.6.ebuild?r1=1.1&r2=1.2 http://sources.gentoo.org/sys-fs/e2fsprogs/e2fsprogs-1.41.3-r1.ebuild?r1=1.8&r2=1.9 http://sources.gentoo.org/sys-fs/e2fsprogs/e2fsprogs-1.41.6.ebuild?r1=1.1&r2=1.2
