[igraph] installation error

[Stephen Davies]

    Hello, I'm on Ubuntu 16.04, and trying to install igraph-python for use
with Python 3 and Anaconda.

    The install via pip seemed to go smoothly via:

$ /home/stephen/local/anaconda3/bin/pip install python-igraph
Collecting python-igraph
Installing collected packages: python-igraph
Successfully installed python-igraph-0.7.1.post6


    But then when I tried to import igraph, I got this:

In [1]: import igraph
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

     36 from igraph.clustering import *

ImportError:
/home/stephen/local/anaconda3/lib/python3.6/site-packages/igraph/_igraph.cpython-36m-x86_64-linux-gnu.so:
undefined symbol: _ZNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEC1Ev

    Any clues?

    Thanks in advance,
