I love this build script -- Rebuild times (with svn up on each module):

18:57 supersff:~/tblds> grep Feb bldlog.txt
Feb 19 18:50:18 building:  trinity-tqtinterface
Feb 19 18:50:27 building:  trinity-arts
Feb 19 18:50:43 building:  trinity-kdelibs
Feb 19 18:53:30 building:  trinity-kdebase
Feb 19 18:56:37 building:  trinity-kdevelop
Feb 19 18:57:25 building:  trinity-kdewebdev
Feb 19 18:57:49 done!

The relevant build() and package() functions of the build script (Arch PKGBUILD
for makepkg) are:

<snip>

_svnmod=kdebase
_svntrunk="svn://anonsvn.kde.org/home/kde/branches/trinity/${_svnmod}"

trinity_prefix="/opt/trinity"

build() {

  cd ${srcdir}

  msg "Connecting to SVN server to update or checkout ${_svnmod}...."
  if [ -d ${_svnmod}/.svn ]; then
    (cd ${_svnmod} && svn up)
    [[ $? -eq 0 ]] || _co_failed=1
  else
    (svn co $_svntrunk ${_svnmod})
    [[ $? -eq 0 ]] || _co_failed=1
  fi

  # if update or checkout failed - bail...
  if [[ $_co_failed -ne 1 ]]; then
    msg "SVN checkout of revision $pkgver -- Complete."
  else
    msg "SVN checkout of revision $pkgver -- Failed or server timeout."
    exit 1
  fi

  msg "Setting PATH, CMAKE and Trinity Environment variables"
  export CMAKE_PREFIX_PATH=/opt/qt:/opt/trinity

CMAKE_INCLUDE_PATH=/opt/qt/include:/opt/qt/include/tqt:/usr/include/dbus-1.0:/opt/trinity/include:/opt/trinity/include/libkrandr
  export LD_LIBRARY_PATH=/opt/trinity/lib:/opt/trinity/lib/kde3:$LD_LIBRARY_PATH
  export PKG_CONFIG_PATH=:/opt/trinity/lib/pkgconfig:/opt/qt/lib/pkgconfig

  cd ${srcdir}/${_svnmod}

  cmake ./ \
    -DCMAKE_INSTALL_PREFIX=${trinity_prefix} \
    -DCMAKE_VERBOSE_MAKEFILE=ON \
    -DWITH_QT3=ON \
    -DQTDIR=/opt/qt \
    -DQT_LIBRARY_DIRS=/opt/qt/lib \
    -DWITH_PAM=ON \
    -DBUILD_ALL=ON
  make
}

package() {
  msg "Packaging - $pkgname-$pkgver"
  cd ${srcdir}/${_svnmod}

  make DESTDIR="$pkgdir/" install

  cd ${startdir}

  # install desktop and update kdmrc and Xsession
  [[ -f trinity.desktop ]] && {
    mkdir -p ${pkgdir}/etc/X11/sessions
    cp trinity.desktop ${pkgdir}/etc/X11/sessions
  }

  _kdmdir=${trinity_prefix}/share/config/kdm
  [[ -d ${pkgdir}/${_kdmdir} ]] || mkdir -p ${pkgdir}/${_kdmdir}

  [[ -f kdmrc ]] && cp kdmrc ${pkgdir}/${_kdmdir}

  [[ -f Xsession ]] && {
    cp Xsession ${pkgdir}/${_kdmdir}
    chmod 0755 ${pkgdir}/${_kdmdir}/Xsession
  }

  [[ -d ${pkgdir}/usr/bin ]] || mkdir -p ${pkgdir}/usr/bin
  cd ${pkgdir}/usr/bin
  ln -sf /opt/trinity/bin/startkde starttrinity

  cd ${startdir}

#   rm -r ${srcdir}/${_svnmod}
}

Note: the package() function includes updated trinity.desktop, kdmrc, Xsession
and links for /usr/bin/starttrinity that allow Trinity kdm to work by simply
modifying inittab, setting initial boot to runlevel 5 and specifying the desktop
login manager as:

x:5:respawn:/opt/trinity/bin/kdm -nodaemon

The trinity.desktop, kdmrc and Xsession being used can all be found here:
