Re: [igraph] install error with python-igraph 0.6

[Tamas Nepusz]

Hi,

Have you added /home/username/opt/lib into your LD_LIBRARY_PATH? If not, try 
this:

$ LD_LIBRARY_PATH=/home/username/opt/lib python -m igraph.test.__init__

If this works, then you have to set LD_LIBRARY_PATH permanently in your .bashrc.
