[solved] How to stop mono from installing?

[doctordruidphd]

I have been running my system mono-free for quite some time, but today's updates are threatening to install it:

The following NEW packages will be installed:
 autopano-sift hugin hugin-data hugin-tools libglade2.0-cil libglib2.0-cil libgtk2.0-cil
 libmono-cairo2.0-cil libmono-corlib2.0-cil libmono-i18n-west2.0-cil libmono-security2.0-cil
 libmono-sharpzip2.84-cil libmono-system2.0-cil mono-2.0-gac mono-gac mono-runtime python-gtkglext1

Near as I can tell, it's the "hugin" package that's trying to pull that junk in, and I don't have hugin installed -- it must be something else that's trying to install hugin. Nonetheless, I don't want mono, or anything that depends on it. How do I prevent it from installing, as far as I am concerned, forever?

Edit: Answered my own question:

sudo -i
echo "mono-runtime hold" | dpkg --set-selections

done deal.
This will only work, however, if you have already removed mono-runtime and its dependencies.
