Does anyone maintain a dependencies map for GNOME? I'm thinking of something like this, but parsable, legible, and current: http://people.freebsd.org/~adamw/gnome_kde_deps/gnome2-lite.png It would also need to indicate how optional components fit together.

I'm not opposed to writing patches that will make the WANT_GNOME ports declare their dependencies predictably. There are approximately 183 ports using WANT_GNOME, so writing these patches is going to take me several days, followed by weeks of waiting for maintainer updates. I might be able to get through this faster by asking the maintainers to assist me, but I expect to have to do most on my own. I'm absolutely willing to abort my misc/gnome-components plan in favour of a better idea. If writing patches for roughly 183 ports is considered a better idea, then this is what I will do instead. It is indeed a problem when a port doesn't respect configure arguments to enable or disable optional features, but exists() causes automatic dependencies. Fortunately, there are two solutions: A. Convince the upstream source that they need to fix this at their end. Sending them a patch is the best way. B. Write a patch that fixes this within the FreeBSD Ports Collection. Such a patch may require upkeep by the port maintainer. >> I'm trying to get this issue resolved as quickly as possible, but I want the >> fix to be done well.

Automatic dependencies make my job much more labour intensive than it needs to be, and the added work increases my chances of making a mistake. pkgng 1.0 was released today, and FreeBSD 9.1 will be released soon, so I'll soon have a lot of upgrading to do. I've grown exceedingly weary of dealing with the problems caused by automatic dependencies, and I just don't want to tolerate it any longer. It's only a tiny minority of ports that declare their dependencies using this unpredictable method, so I've decided to weed them out to make my life easier. -- A.J.
