How about these versions:
Code:
apt-cache policy libgii0
libgii0:
  Installed: 1:0.9.1-0.1
  Candidate: 1:0.9.1-0.1
  Version table:
 *** 1:0.9.1-0.1 0
        930 ftp://ftp.fi.debian.org testing/main Packages
        990 ftp://ftp.fi.debian.org unstable/main Packages

apt-cache policy libggi2
libggi2:
  Installed: 1:2.0.5-1.1
  Candidate: 1:2.0.5-1.1
  Version table:

        930 ftp://ftp.fi.debian.org testing/main Packages
        990 ftp://ftp.fi.debian.org unstable/main Packages
If the debian box hasn't internet you can search at http://www.debian.org/distrib/packages#search_packages within testing and unstable branches, and check the packages dependencies so you can download those as well. For example this http://packages.debian.org/testing/libs/libgii0 page says the dependencies are:
