Thanks, Joaquin, but I've seen all these articles since I spent the entire weekend trying to get my topology to run on CentOS/Python2.7. Getting it to work on Mac OSX was a breeze because I can easily install Python 2.7 on it.
It'd be great if somebody with the actually CentOS/Python2.7 experience could share their thoughts.
