looking through the sources file, and just wondering *ahem* -- exactly how does this work? For example - imagemagick has a dependency of libpng2-dev. However, there is no package entry for libpng2-dev inside sources. There is however, a 'Binary' entry of libpng2-dev under the Package heading of libpng2. Is it true that these are synonyms for each other? If so, why? Why not combine the binary and package entry into one header? Ed
