MegaGlest 3.4.0 has been released yesterday for Ubuntu 10.10, and dependencies only allow to install it on Ubuntu 10.10 because of library version requirements marked on packages.
Steps I followed to install MegaGlest 3.4.0 in Ubuntu 10.04 (when I already had previous version installed):
Download packages from a mirror:
http://mirrors.dotsrc.org/getdeb/ubuntu/pool/games/m/megaglest-data/http://mirrors.dotsrc.org/getdeb/ubuntu/pool/games/m/megaglest/And then install with the terminal commands:
sudo dpkg --force-depends -i megaglest-data_3.4.0-1~getdeb1_all.deb
sudo dpkg --force-depends -i megaglest_3.4.0-1~getdeb1_i386.deb
MG 3.4 works ignoring high dependency versions.
Then I suppose that setting lower versions in dependencies is the only step needed to rebuild compatible packages for lower Ubuntu versions.
