After you build GraphicsMagick from source, you will need to rebuild Octave
with your new build of GraphicsMagick.  The fact that trying to uninstall
GraphicsMagick with your package manager is uninstalling Octave suggests me
that you are using Octave from your package manager, not the one built by

I believe the only distro still distributing GraphicsMagick built with
quantum depth 8 is Debian so I am guessing you are using Debian or one of
its derivatives (such as Ubuntu). You can find details on how to build
from source on the Octave wiki [1] but either way, leave a comment on the
Debian bug #557879 about this [2] so we can stop recommending Debian users
that do image processing to rebuild Octave from source.
