Issues downloading Graphlab dependencies get_dependencies()
<p>I am having trouble when I try to download the dependencies needed to run <code>graphlab</code>. I do <code>import graphlab</code> I get the following:</p>

<pre><code>ACTION REQUIRED: Dependencies libstdc++-6.dll and libgcc_s_seh-1.dll not found.

1. Ensure user account has write permission to C:\Users\DANISUAR\AppData\Local\Continuum\Miniconda2\envs\gl-env\lib\site-packages\graphlab
2. Run graphlab.get_dependencies() to download and install them.
3. Restart Python and import graphlab again.

</code></pre>

<p>So I try to run <code>graphlab.get_dependencies()</code> and I get the following error:</p>

<pre><code>In [2]: gl.get_dependencies()
