This suggests that you do not have a compiler installed, or it's not
installed correctly.

If you run "g++ --version", what output do you get? What Linux
distribution and version are you running (run 'cat /etc/issue' if you
don't know)?

On Debian or Ubuntu systems, installing the 'build-essential' package
should provide everything you would need. I don't know the equivalent
on Redhat or Suse.
