This is not a standard Debian / Ubuntu builds - it is Tim's builds on Trinity build-farm.
Luck you. :)
By the way, in the Debian Wheezy is officially LibreOffice 3.5.4 :) However, in wheezy-backports and Jessie is already 4.1.4.
I have 4.1.4 installed from a third party Slackware repo, but there is no Trinity support. Asking to add that support would be a waste of time as Trinity is not part of the "official" Slackware eco system. All desktops not supported in the official releases must be maintained by interested third parties.
This is why I filed the bug report and want to see a mini how-to posted to the wiki. Those who are faced with compiling LO on their own need all the support they can get.
