<p>Error is to big to copy it all. So I just copied the beginning and the end.</p>

<p>You need to install the Python development files. I think it will work. Try </p>

<pre><code>apt-get install autoconf g++ python2.7-dev 
</code></pre>

<p>Or</p>

<pre><code>sudo apt-get install python-dev
</code></pre>

<p>Either one of the above and then this below one </p>

<pre><code>pip install pycrypto
</code></pre>

python pip pycrypto
