I am right apart from what exactly? What is exactly wrong with FreshPorts results? RUN_DEPENDS are package dependencies. They cause conflicts even for people that do not build on the machine the package is supposed to run on. Grepping with your command, I get 153 dependencies that are not just build dependencies. Some of them are optional, that is the main reason FreshPorts having lower numbers. find /usr/ports -name Makefile | xargs grep ImageMagick6 | grep -v BUILD | wc -l That is by no means the best approach (using the INDEX or the result of a package builder would be more useful), but it is your command. It does not matter what you believe is easily fixable. I just stated what is broken now, which was not broken before your commit. Granted, the chain I listed leading to kde5 has an optional dependency in it that is not default, but the default packages of calligra and inkscape are affected (and there are probably more people than just me having dvdauthor depend on ImageMagick6 as it is needed for basic operations and dvdauthor is not optional for kde5). Anyhow, as long as you do not work recursively, your search does not tell you which conflicts you create and you have no chance to find the chain I listed leading to kde5. The ImageMagick7 port is five years old. Still many ports depend on ImageMagick6. For me, this suggests that the change is not trivial or not wanted. (For example, Debian has all dependencies on 6, too.) You fixed the conflicts of emacs with some ports, but broke it for many many people. The first group has workarounds, the seconds does not. As I know FreeBSD, consequences of changes negatively affecting many people are evaluated first. If people forget to do that or make mistakes in their evaluation, they usually revert their change for the duration of a proper evaluation. I am not into fixing ImageMagick dependencies, I just told you that I think you broke the setup of many people. Reverting your change, you could introduce a non default option for emacs to depend on ImageMagick7 instead of ImageMagick6, but I am in no position to tell you what is best here.
