I looked at the status of packages that I mentioned. It appears that both are longer abandoned and that is not used practically nobody than Trinity. It can therefore be assumed that the packages will not be updated and no longer put back into the distribution.

Well, apparently we must decide how to leave these dependencies.
I looked for corresponding packages in openSUSE repos. There is a poster package containing a script for printing of posters, but nothing resembling that described on https://www.gnu.org/software/gift/ which was last updated in 2011.
