I have removed gentoolkit, and it still fails:

emerge --ask --update --newuse portage
[...]

The current version of portage supports EAPI '5'. You must upgrade to a
newer version of portage before EAPI masked packages can be installed.


So how do I update portage??  Apparently, it´s impossible to update portage
before updating cryptography, and cryptography cannot be updated before
portage has been updated.  I would say that this is a bug.

I added 'python_target3_4' to the global use flags before doing this.

emerge --version
Portage 2.2.14 (python 2.7.9-final-0, default/linux/amd64/13.0/no-multilib, gcc-4.8.3, glibc-2.19-r1, 3.17.8-gentoo-r1 x86_64)

It´s not possible to install gentoolkit now, so I can´t tell which USE flags
are used for emerge.
