How did you get ROOT.CERN ? Is it from the ebuild or from a non-Gentoo binary package ?

I guess this is a non-Gentoo package.

It is recommended to use the versions from portage, and there is a bump request for sci-physics/root-6.00.02 in bugzilla, and this is now in the Science Overlay

I installed root using gentoo-science overlay.

[xaviermiller]

It seems you have changed of GCC version between the compilation of root and cling, regarding of this: https://sft.its.cern.ch/jira/browse/ROOT-5961

Re-emerge cling with the new version of GCC, or re-emerge your system.
