Cannot install Bastion

On install I kept getting an error that the package libsdl-gfx1.2-4 was installed, even though libsdl-gfx1.2-5 was installed.

You can get the link to the older library package from here:

http://www.ubuntuupdates.org/package/core/trusty/universe/base/libsdl-gfx1.2-4

So for my system, installation went like this:

wget http://security.ubuntu.com/ubuntu/pool/universe/s/sdlgfx/libsdl-gfx1.2-4_2.0.23-3_amd64.deb

sudo dpkg -i libsdl-gfx1.2-4_2.0.23-3_amd64.deb

sudo dpkg -i bastion_1.4-0ubuntu1_amd64.deb
