This post got me curious about the new installation script linked by Gustaf, so I gave it a try.
I can report proper working of the script on Debian Jessie, installed from scratch with the minimal set of software, with only two minor issues: 'make' should be included in the software requirements for naviserver script, while sudo should in the openacs one (Debian by default doesn't install sudo).
Given how easy has been to have the system up and running I suggest Mattia to try this method, as it also gives you the latest possible version to play with.
Great job guys!
