In Arch Linux you need to install the following packages:

pacman -Sy subversion bzip2 libxslt libxml2 libjpeg \
           libungif shared-mime-info mesa boost dbus \
           openssl pkgconfig xine-lib clucene redland \
           gpgme hal cmake qt qca

Note that Qt 4 will be installed by the command above (it is required by QCA anyway), but you can build your own from qt-copy in KDE svn, which will include several fixes not yet in a released version of Qt as well as giving you the option of compiling a version with debugging information. If you do this, the system installed QCA (and any other system libraries that use Qt 4) should work without a problem in your local KDE build.

All of the dependencies in kdesupport can be installed from the [extra] repository. These will be fine for building from the KDE stable branch, but some may be too old for building KDE from trunk.

pacman -Sy automoc4 akonadi eigen taglib soprano strigi qimageblitz phonon

To build the latest versions of these instead, see building kdesupport

For the makeobj script, you can either install kdesdk from [extra] or just download http://websvn.kde.org/*checkout*/trunk/KDE/kdesdk/scripts/makeobj and copy it to either /usr/bin or $HOME/bin (providing $HOME/bin is in your PATH).

Note that there may be other optional dependencies of KDE modules, but almost all of these can be satisfied by [extra], [community] or the AUR. The missing optional dependencies will be listed when configuring a package with cmake. To search and install from all the main repositories and the AUR at the same time, you can use Yaourt.
