I have the same problem, and changing from python2.7 to python3.4 fixes the problem. This is only a workaround.
This is fixed in the master branch: https://gitweb.gentoo.org/proj/portage.git/commit/?id=ab7efe823ace977d8b46f324bdcbf44dcb7ca6d9
I have this problem too on various systems 3bit/64bit, kvm, lxc .... switching to python-3.4 is the only thing that helps

*** Bug 566712 has been marked as a duplicate of this bug. ***
Just encountered this on a server I was @world upgrading. The server was running portage 2.2.25 when if had the problem (same error as Konstantin reported relating to pulling in the sys-process/nmon-15h update), but updating to portage 2.2.26 seems to have fixed it for me.
Fixed in 2.2.26.
