yum: "gocr dependency missing"

[Aldo Foot]

I was updating my system using my local yum repo, and everything
was ok except for the e2fsprogs updates; yum complained "gocr
dependency missing"
and it would bail out.
So in my local repo I disabled the Base part of it and left the
Updates enabled and then
selected the actual Fedora Base repo. With this the gocr dependency
was installed.
The same thing happened for several kdegraphics packages.

Why did the gocr needed the "real" F8 Base package repository to install?
