There are several other environment variables that need to be set to
achieve full isolation.  These are set in a script which is run automatically
as soon as I "cd" to my programming work-area, thanks to a special "cd"
function in my ~/.profile.  I can have more than one such area, each with
its own setup.

With apps, I do not worry about versions of KDE apps and daemons, unless
perhaps the app is complicated by having plugins and KParts.  It turns out
that the daemons and background processes needed to run an app are
not running continuously, but only occasionally as a result of library calls
made by the app (e.g. if Palapeli requests a plugin to slice a new puzzle).

The only thing that runs all the time is central DBus, apparently.

A dedicated user account is recommended by the manual for kdesrc-build.

I tried it, but did not get very far.  It failed on git setup and repository access,
but should work if you are going to use anongit.  I think it will give you private
ownership of processes you may start indirectly, but everyone gets the same
central DBus, MacPorts, etc. which are owned by root.

Cheers, Ian W.
