It looks like your build may be picking up conflicting versions of "gcj" and "c++". This can happen if you install a new gcc somewhere, but still have an
older one on your PATH somewhere that doesn't have "gcj". Modify your path to make sure that the gcc/c++ frontend commands are running from the same
place.
