Cannot set proper environment for Digikam beta

[Dotan Cohen]

As I've built Digikam 0.10 beta from SVN on KDE 4.1 beta2, I need to
set it's environment manually. I've just been guessing at values such
as these:
export LIBDIR=$DIGIKAMKDE4:/usr/lib/kde4
export DBUSDIR=$DIGIKAMKDE4:/usr/lib/kde4
export KDEDIR=$DIGIKAMKDE4:/usr/lib/kde4
export KDEDIRS=$DIGIKAMKDE4:/usr/lib/kde4
export KDEHOME=/home/hardy/.kde4
export KDETMP=/home/hardy/tmp/hardy-kde4
export KDEVARTMP="/var/tmp/hardy-kde4";
export LD_LIBRARY_PATH=$DIGIKAMKDE4/lib:/usr/lib/kde4:/usr/lib/kde4/lib
export LDPATH=$DIGIKAMKDE4/lib
export LD_LIBRARY_PATH=$DIGIKAMKDE4/lib
export QTDIR=/usr/lib/qt4
export QT_PLUGIN_PATH=/usr/lib/kde4/lib/kde4/plugins
export PKG_CONFIG_PATH=$DIGIKAMKDE4/lib/pkgconfig:/usr/lib/kde4/lib/pkgconfig
export PATH=$DIGIKAMKDE4/bin:$PATH

How can I find out what these values really are supposed to be?
Digikam starts but has io errors because of the wrong environment:

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?
