I cannot get Kajongg to run in my build, perhaps because it is
a Python program and I know very little about Python or perhaps
there is something Pythonesque missing from my build.

I like to (have to?) build the latest KDE and Qt trunk, especially
just before a release, in case of library changes affecting my code
(I am getting quite paranoid about those), but also to keep up with
developments in other KDE Games, which (maddeningly) will not
compile, in some cases, unless you have the latest trunk libraries.

Like you, I would much prefer to stick with an older set of libraries for
a year or two and that has always been my practice (in industry on UNIX
servers) before I retired and joined KDE Games.  You get much more
application development work done that way - and happier end-users.

All the best, Ian W.

P.S. In my last job, I was one of the key players who monitored up-and-
coming changes to libraries and software and worked out when, if and
how best to introduce them.  It involved a lot of testing and benchmarking
of existing applications against new software, but only for a few of us.
