Working through installing gnucash 2.3.15 from source.

the process I've followed is this:
downloaded gnucash-2.3.15.tar.bz2 to /usr/src/
cd /usr/src/
sudo tar -jxvf gnucash-2.3.15.tar.bz2
cd gnucash-2.3.15/
sudo apt-get install intltool libglib2.0-dev guile-1.6-dev libgconf2-dev
libxml++2.6-dev
./configure --enable-python-bindings

I get this error that I dont know how to resolve
