Hi, I am responsible for this bug, it happens when you do an incremental build of sage (i.e. you are upgrading a prior version of sage rather than building from scratch). It doesn’t happen on build from scratch or when you are using compilers from the system. A fix is being reviewed at https://trac.sagemath.org/ticket/24694 Note that if you want to try it you’ll need autotools and related packages to be installed.
