Hallo.
I have just encountered many missing important packages in the openSUSE:Factory sources.
For example: freetype2 libxml2 libxslt libgalago libgalago-gtk nvtv
It seems, that all these packages are of type "one source repository, more spec files" in the Autobuild sources repository.
I have a shell script, which could help with mirroring of such packages using osc link. I used it for mirroring of GNOME:UNSTABLE in past. Feel free to contact me if you are interested.
