Hi Sebastien,

Unfortunately, that doesn't seem to solve the problem for me...

I apologize ahead for being ignorant of this kind of problems, but is 
this due to namespace conflict?  I am in the process of moving toward 
CGAL 3.7 or later, but admittedly, the migration process is a bit slow, 
and I would like to have a temporary fix (if possible) for the current 
version.

Thanks again!

Frankie
