Can't install pyethereum module
<p>I'm new in Ethereum, so probably that's a silly question.</p>

<p>Now I'm trying to install serpent and pyethereum according to this <a href="https://github.com/ethereum/wiki/wiki/Serpent" rel="nofollow">tutorial</a>. Everything works well, but when I'm launching Python's code:</p>

<pre><code>import serpent
import pyethereum
</code></pre>

<p>There is an error: <code>No module named pyethereum</code></p>

<p>How can I solve it?</p>

<p>Follow the installation instructions from <a href="https://github.com/ethereum/pyethereum" rel="nofollow">Pytherium's Readme</a>, which read:</p>

<pre><code>git clone https://github.com/ethereum/pyethereum/
cd pyethereum
python setup.py install
</code></pre>

<p>In the tutorial's instructions, <code>develop</code> branch is used, which seems to be failing according to the continuous integration badges.</p>
