I just tried to reinstall on my Fedora 24 machine but I couldn't locate the gfortran needed for OpenBLAS. I edited the corresponding CMakeList to include the /usr/bin/ directory where my gfortran is, but it couldn't help. Otherwise, I set up the main CMake project correctly, the error appeared when Elemental downloaded OpenBLAS and wanted to build it during "sudo make". Do you think, I should try installing OpenBLAS differently and let Elemental find it? I tried Elemental previously (a few months ago) on my Ubuntu 14.04 and it worked well.
