by loading cedet-remove-builtin.el, but I realize now that it will only
remove *one*. You however had *two* (the one shipping with Emacs and the
one installed by Gentoo), so when the first one was removed, the second
one kicked in. I've now changed cedet-remove-builtin to remove any
further CEDET installations from the load-path, which should hopefully
avoid such problems in the future.
