    It looks like the gnu c++ compiler (g++) can’t be found. Try typing:

    root@sinskey-14 rosetta++external link#which g++

    There should be a symbolic link /usr/bin/g++ pointing to the output of the above command.
    If there was no output, I would suggest running the following command as root:

    root@sinskey-14 rosetta++external link#yum install gcc-c++

    Before compiling, check the compiler install, by running which g++ again.
    I have compiled Rosetta successfully with g++ 4.1.2.

    Be sure to run make clean before re-compiling.
