Portage 2.2.14 (python 2.7.10-final-0, hardened/linux/musl/arm/armv7a, gcc-4.8.4, musl-1.1.8, 2.6.28.10-power53 armv7l) For more information about Blocked Packages, please refer to the following section of the Gentoo Linux x86 Handbook (architecture is irrelevant): http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?full=1#blocked
I assume this bug is about a bad URL in Portage output for failed merges, pointing to the old GuideXML handbook, when it should link here: https://wiki.gentoo.org/wiki/Handbook:X86/Working/Portage#Blocked_packages
This is fixed since 2.2.16: https://gitweb.gentoo.org/proj/portage.git/commit/?id=17bc89c5db424c3f04af28a1da5bf90a943ac368
