Hi Tiego, Thank you so much for helping us out! You were right, CGAL were not properly configured on the server. Instead of building everything from source on CentOS7, I built graph-tool-2.8 instead of the latest release, following the step-by-step directions here: https://gist.github.com/sbonner0/2138f2e3e2b249df51c765e1656f9d48. I hope this link will help others in similar situations. Much obliged, Yu On Wed, Jun 29, 2016 at 3:00 AM, <graph-tool-request@skewed.de> wrote:

CGAL version: 4.9

This might be some incompatibility with version 4.9. I will investigate.

In the mean time, you may downgrade to version 4.8, which should solve the problem.

Best, Tiago
