[petsc-users] [3.7.5] strange config error on macOS with XCode 8.3 and Clang 8.1.0

[Unal]

In my experience, each time you update Xcode, you also have to update the Command Line Tools (https://developer.apple.com/downloads/index.action?=command%20line%20tools <https://developer.apple.com/downloads/index.action?=command%20line%20tools>), and reinstall everything again in the right order; in my case, I have to reinstall Fortran, MPI, HDF5 and PETSc. When one doesn't do it in the right order, it appears problems like what you reported.
