Hi,
If someone is interesting for mapping and texturing with trenchbroom, i found something interesting.
1 - Extract the zip in your TrenchBroom\games
2 - Configure your Darkmod folder in games settings.
Now you can see the texture in your texture browser.

3 - Make a room and texture it.
4 - Save your map and open it with notepad++
5 - Delete line 6 ( "_tb_textures" .... ) and all the _ed with replace fonction.
6 - now import the map in DR, add light + player start and compile.
Done.
