[igraph] Import error in igraph

[Shreya Kedia]

Hello,

I have been using igraph for a few days, and it worked perfectly fine until today. When i tried to execute one of my previously working codes, i got this error:

Traceback (most recent call last):
  File "conductance.py", line 2, in <module>

    from igraph import *
  File "/usr/lib/python2.7/dist-packages/igraph/__init__.py", line 30, in <module>
    from igraph.core import *
ImportError: /usr/lib/python2.7/dist-packages/igraph/core.so: undefined symbol: igraph_community_leading_eigenvector_naive

Can you tell me what's wrong?
