gcloud problems with pip install
<p>I am running an ubuntu 14.04 instance on google's cloud compute engine. I have installed anaconda (python 3.5.0) and want to install additional packages via pip and also upgrade some manually.</p>

<pre><code>pip install arch
</code></pre>

<p>I get the following error</p>

<p><code>Command "/opt/anaconda3/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-10ckqqqa/arch/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-tsgsc6n0-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-10ckqqqa/arch/</code></p>

<p>Other packages (<code>seaborn</code>, <code>pymysql</code>) were install without problems via pip. First I thought it is related to the <code>arch</code> package but I also noticed updating <code>pip install numpy --upgrade</code> raises an error as well, with the following error:</p>

<p><code>Command "/opt/anaconda3/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-5hogbswt/numpy/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-xrahrzqb-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-5hogbswt/numpy/</code></p>

<p>The source of the problem is most likely not library dependent, what do I miss here to get the instance properly working ?</p>
