Re: [igraph] Installing python-igraph on a Linux machine

[Alessandro Antonucci]

You are completely right.

In fact there was an other rpm-based version of igraph
on my system. I've removed the rpm, and copied the
libigraph.so.0 in the /usr/lib directory.

Now everything works fine.

Thanks a lot for you answer (and sorry for the stupid question).

Best,

Alessandro
