[igraph] MAtlab/igraph conflict?

[Alessandro Antonucci]

Dear Igraphers,

I'm running a Python script based on (Python)igraph
in a linux environment. This script should interact with 
Matlab, but, if I try to run the script from Matlab, by a 
(Matlab) command like:

system('python script.py')

I receive the following error:

ImportError: /opt/matlab/sys/os/glnx86/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by /usr/lib/libigraph.so.0)

I've also noticed that if I run the script as a superuser, which means
if I run Matlab as a normal user, but I run the command:

system('sudo python script.py')

everything works fine.

Any idea about what is going wrong?

Best,

Alessandro
