You are using g++ from FractalKit. When compiling with g++ the resulting binaries need to find
the linked libstdc++.so.6:

configure:2800: ./conftest
ld.so.1: conftest: fatal: libstdc++.so.6: open failed: No such file or directory
./configure: line 2802:  4779 Killed                  ./conftest$ac_cv_exeext

This is located in /usr/local/lib/sparcv9 and needs to be added to the runpath of the resulting
binary e.g. with
  export LDFLAGS=-R/usr/local/lib/sparcv9

I don’t know why it worked before.


Best regards
