adding a language on a private build

hi

assuming I translated all my oo-2.0-xx-GSI.sdf file...
And I want to make a private build, with all files patched for adding my 
language
There's one more step: dispatch all strings in all localize.sdf files. 
Am I wrong?
Where to find doc on this?

I allmost finished building the O2beta src...
if I patch files for adding a language, should I rebuild all?
I read: "Note that you can only build the language packs *after* you 
have build the complete office with all selected languages."
ALL selected languages????

info: I build on linux, with an old P2 (6 days to build!)

how to manage dependencies (ex how to build "until transex3") ?
Read the project_dependencies.png and empty unxlngi4.pro dirs to have 
them build?

thanks
