the most recent unmasked cmake in the portage tree is unable to find python >= 3.3. This was fixed upstream in https://github.com/Kitware/CMake/commit/ab6201ab647c13fee44c44822b8502e9848faaaf The first tag where this commit is included, is v3.0.0, which is currently masked. Possible solution suggestions: 0. Apply a quick and dirty patch that adds python 3.4 to the FindPythonLibs.cmake file, and release that with cmake-2.8.12.2-r2. 1. Unmask cmake-3.0.0, but is probably was masked for a reason.
Created attachment 382594 [details, diff] patch that fixes the issue upstream commit that adds python 3.4 to the search paths.
