If I recall correctly, building gfortran also requires flex and building flex requires bison and building bison requires m4 and the download_prerequisites script didn't download any of those the last time I checked. I realize that building gfortran from source comes very easily to GCC developers, especially if they do it regularly. I've encountered a lot of people who found it challenging, including myself initially, which was the reason for incorporating the capability into the OpenCoarrays installer. Damian
