Both are currently highest version in ~amd64. Portage unfortunately does not autoresolve this kind of circular deps, even though any lower version of cmake or jsoncpp should be sufficient. 1: https://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/dev-libs/jsoncpp/jsoncpp-0.10.1.ebuild?revision=1.1&view=markup 2: https://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/dev-util/cmake/cmake-3.2.1.ebuild?revision=1.1&view=markup
Unless cmake can make json support optional, I guess we need some kind of USE=build or other bootstrap.
cmake can optionally use its own bundled copy of jsoncpp. -DCMAKE_USE_SYSTEM_LIBRARY_JSONCPP=OFF
This blocked me for a bit. Why is cmake such a nightmare? another gem: qt depends on cmake and cmake depends on qt...:( At least I can use USE flags to work around it.

Hit by this. There's no way to unloop this, even with useflags. What can be done ? I can't update/install anything on the system now .. ?

Try (temporarily) adding >=dev-libs/jsoncpp-0.10.1 to /etc/portage/package.mask until you have upgraded cmake.
or you can do this : emerge =dev-libs/jsoncpp-0.6.0_rc2 -1
Since the ongoing bikeshed is not going to help users... + 14 Apr 2015; Michał Górny <mgorny@gentoo.org> cmake-3.2.1.ebuild, + metadata.xml: + Add USE=internal-jsoncpp to solve circular dependency, bug #546130
+ 14 Apr 2015; Mike Gilbert <floppym@gentoo.org> cmake-3.2.1.ebuild: + Fix mgorny's change; wrong variable name.
