In order to use kghostview, I download the page from here. After that, I run the following command:

sudo dpkg -i kghostview_3.5.10-0ubuntu1~hardy1.1_i386.deb

However, I have the following error messages:

dpkg: dependency problems prevent configuration of kghostview:
 kghostview depends on gs; however:
  Package gs is not installed.
 kghostview depends on kdelibs4c2a (>= 4:3.5.8-1); however:
  Package kdelibs4c2a is not installed.
 kghostview depends on libqt3-mt (>= 3:3.3.8-b); however:
  Package libqt3-mt is not installed.
dpkg: error processing kghostview (--install):
 dependency problems - leaving unconfigured

It seems that I should also install some external packages such as gs, kdelibs4c2a and libqt3-mt. However, I do not have any idea of how to install them. I try the sudo apt-get install command, but fail. Any idea will be appreciated.
