Build PoDoFo

VER=0.7.0
wget http://downloads.sourceforge.net/podofo/podofo-$VER.tar.gz?use_mirror=osdn
mv podofo*.gz /tmp
cd /tmp
tar xzvf podofo*.gz
cd podofo-$VER
cmake .
make
make install

Make some directories:

mkdir ~/scribusinstall
mkdir ~/scribussource

Finally build Scribus:

SRC=~/scribussource/$VER/Scribus
cd ~/scribussource
svn co svn://scribus.info/Scribus/branches/$VER
mkdir -p $SRC/builddir
cd $SRC/builddir
cmake .. -DCMAKE_INSTALL_PREFIX:PATH=~/scribusinstall
make
sudo make install
cd ~/scribusinstall/bin
./scribus
