My advice is: forget swaret, and do your own research into dependencies. IMO, swaret goes against the basic principle of Slackware, which is to use your own independent brain.
What you describe is total madness. Welcome to dependency hell.
The problem with a lot of the slacky.eu at present is that they have Gnome dependencies because the package builders have installed Gnome-slacky. That makes these packages useless for vanilla Slackware. Better would be to use the SlackBuild scripts and build the packages from their sources. Look at
http://slackbuilds.org/ for an extensive collection of build scripts - and slacky.eu provides sources and a SlackBuild script too with all their packages.
