Hi, I tried to build the experimental texlive-bin (2007) on my ibook and the process failed with this error: dh_installtex: Specified flavor format:build_all not supported. The update of tex-common to the experimental version (1.3) solved the problem and texlive-bin then compiled fine. Thus, I supposed there's a too low versioned dependency on tex-common for texlive-bin 2007. Sincerely, Yannick
