I am not sure what the problem is. Any thoughts? Thank you.

Answer 1

The problem was there were other /bin/ directories that had older versions of gcc and openmpi. When updating, the new files from /lib/ directories needed to be trasnfered to the /Cellar/ directories. The problem is fixed when first uninstalling all old macports and compilers with incorrect files and/or paths as sudo port -fp uninstall installed , and brew uninstall openmpi , and brew uninstall gcc . Then reinstall new homebrew compilers brew install gcc , brew install openmpi . This gives the correct paths with configured files when submitting a make file.
