[FINAL EDIT / SOLUTION SUMMARY]
Following what follow you will get it
Important Note : i have replace build by install from my initial post and add extra info, because should be the same! Now in my case i can build (special folder) and install synfig last dev .deb (like other software).
Original post was not a 1 april joke 
In order to install synfig last cairo development in ubuntu 12.04 familly (x/l/k/t�..) and should work the same with all .deb linuxlike.
Another boring Note - Working this things, always work better with an updated systemâŠ
First : How to upgrade libcairo2 and libcairo2-dev up to 1.12 if not present in my repository ?
Adding âquantal mainâ (ubuntu 12.10) repository can be a solution.Take care to select manually only the .deb needed - libcairo2 and dependencies (or this will be the road to full system migration) - after this little update ,7 .deb or something like, donât forget to disabled or suppress âquantal mainâ repository to preserve your system!
Second :
Another other boring note - Conflict can occurs âŠ!
Libcairo2 1.12x can cause text render issues in several application, for me was in LibreOffice from 3.?x to 4.0xx
To correct this problem, i have upgraded xorg-server (was 2:1.11 now is 2:1.13) solution from here . Done by enabling momently quantal repository.
I hope this can help.
[FINAL EDIT / END / SOLUTION SUMMARY]
Everything all right !!! ???
[EDIT 04/02] YEP ! [END EDIT 04/02]
héhé. quite 2/3 all right !
So after upgraded libcairo to > 1.12 (has iâm on precise 12/04 x, i activated quantal 12/10 repository for a while)
I builded with same build.sh has mentionned in how to ubuntu 9.10 thread who well worked before merge.
This is output from Synfig-studio (cause core make successfull !!!)
