imagemagick builds with libpng-1.4.0beta16, the results are at: http://people.debian.org/~anibal/imagemagick/ I'll intend to upload libpng_1.4.0~beta16-0 to experimental. The transition to the new libpng soname will be problematic as there is a considerable number of reverse dependencies and there is also a number of circular dependencies involving libpng. IMHO, the release managers will not approve this transition. Aníbal Monsalve Salazar -- http://v7w.com/anibal
