But uninstalling and reinstalling still ended up with configure using "cc" (system clang) as a gcc compiler, despite what the ports infrastructure reported (shown above). So phoronix-test-suite ends up using clang to compile benchmarks unless one adjusts install.sh scripts manually and then uses the adjusted script to rebuild code.
