OK, I think I've resolved the Kino problems. It doesn't need any X.org-7.2 files to build or run. I reinstalled VL 5.8 to return to a clean system, and installed all the packages in Dweeberkitty's collection except pth. I also needed to install texi2html from the repos.
After this Kino built with no issues and seems to work fine. I'll upload this version to my vectorcontrib directory shortly.
I suspect that the X dependency problems which Dweeberkitty found were resolved here by installing the xproto and xextproto packages. I did slightly mess these up by building them as TGZ instead of TLZ, but they install just fine anyway.
