Answer 1

Try updating setuptools:

easy_install -U setuptools

Answer 2

This error indicates that easy-install cannot find the package, which means that it was not found. You better install the dev package through the distribution package manager (apt-get, etc.)

If you carefully study the output, pay attention:
