[igraph] installing igraph 0.53 on Ubuntu 10.04

[Arun]

I noticed that igraph is in the repository for Ubuntu Lucid 10.04.

I did this:

sudo aptitude install libigraph0

This seemed to work fine and installed igraph 0.53.

I, then, did this:
sudo easy_install python-igraph

And, I get this error:

Any suggestions on what's wrong?
