Created attachment 448374 [details] build.log As of Qt 5.7, revdeps must be build with C++11 or later.
The actual error message in the log looks like this: error "Qt requires C++11 support". Reported upstream: https://github.com/litecoin-project/litecoin/issues/253
I found, that enabling C++11 explicitly might solve the problem. Running emerge with the following command should be a workaround for this bug: CXXFLAGS="-std=c++11 $CXXFLAGS" emerge -v net-p2p/litecoin-qt I'll try it out myself as soon as I updated my env to QT 5.7.
Indeed, Qt 5.6 makes C++11 mandatory however there is still a failure after manually building with c++11.

This ticket was marked as IN PROGRESS on 2016-09-28. Are there any news?
The bug https://bugs.gentoo.org/show_bug.cgi?id=594686 is resolved, which means this bug should be fixed as well, since it always was a duplicate of the aforementioned. Due to a lack of time and computing resources, I cannot verify that personally. Please leave a comment or reopen the bug, if it is not fixed. *** This bug has been marked as a duplicate of bug 594686 ***
This is not a duplicate of bug #594686. That bug is about a build failure when C++11 is used, this bug is about a build failure with >=Qt 5.7 and C++11 is *not* used.
This package is now broken even for stable users unless they mask Qt 5.7.
