For some reason gmane isn't posting the responses to my query. I didn't realize you guys had responded until now, many hours later, when I decided to check at: http://lists.fedoraproject.org/pipermail/kde/2010-January/005358.html - So, I guess, as was pointed out, I do sometimes need bindings, even merely to run a program, not only to write it. Is there a way to know which of the myriad bindings packages I need to install on my system? I realize that yum ought to take care of it when I install or update, but... What about when I run rpm -e some-binding? Does rpm know that some-binding.rpm was pulled in by yum for some other program? I had a fair number of these bindings on my system, of the form x-python, y-python, z-python and so on. I never explicitly installed them, so yum must have pulled them in as dependencies for some program, but when I installed kde-4.3.90, there were problems that I managed to resolve with rpm -e x-python y-python z-python etc. rpm allowed me to remove them, so what happened? Did rpm 'forget' that they were dependencies, or are they no longer dependencies?
