  That would generate error messages.  The best solution is to get rid
whatever is pulling in KDE.  As for blocking stuff to pull in, to quote
Frank Sinatra, "I did it m-y-y-y-y-y way".  I wrote a script,
/etc/portage/cleanup which generates /etc/portage/rsync_excludes on my
machines.  Note that the groups listed are what I don't use.  Your
machine(s) will probably have a different set of unnecessary stuff.


#!/bin/bash
remove() {
rm -rf /usr/portage/${1}/ /usr/portage/metadata/md5-cache/${1}/
echo "${1}/" >> /etc/portage/rsync_excludes
echo "metadata/md5-cache/${1}/" >> /etc/portage/rsync_excludes
}
#
# Remove rsync_excludes

I mentioned the GUI in case there were people who preferred it. The CLI 
equivalent is wpa_cli of course.  ;-)

I'm still working on this, but wanted to thank you for your input.
I like help that has an outline of how to go at something.

Very helpful.. and I seem to be close to getting this cleaned up.

I despise NetworkManager.  Over the years, it has been the cause of
countless problems and hours of wasted time.  The first I do when
dealing with network problems on *buntu systems is uninstall
NetworkManager.

Which is spelled "emacs /etc/wpa_supplicant.conf

You could also try to stop portage from even syncing the KDE components
into the tree. I usually do this for small systems to not give portage
any chance of pulling in unwanted components. As a plus, syncing and
dep calculation should be faster.
