This is a well-known problem with libgcc_s.so.1 and gfortran. You can state whatever you believe should happen, but it does not seem to work that. You have a few options: 1) Add -static to your options; 2) Use LD_LIBRARY_PATH, LD_RUN_PATH to point to /usr/local/lib/gcc8; 3) Add -Wl,-rpath=/usr/local/lib/gcc8 to FFLAGS in /etc/make.conf (check syntax for this one); 4) bump the major library version number for /lib/libgcc.so.1 to 2; 5) fix rtld to not fail on the first found library in the cache. Iterated over all entries and only fail if the library isn't found; 6) rename /lib/libgcc_s.so.1 to /lib/libllvm_s.so.1 and teach llvm/clang/rtld to not misappropriate a well-known GCC library name. -- Steve
