Gtk3 installation - gtk3

Question

I'm trying to install gtk+-3.2.3 on Ubuntu natty. This is a fresh Ubuntu install with security updates only. I have not installed any new versions of gtk. I just have gtk2, that Ubuntu comes with. First I installed the following:
sudo apt-get install libffi-dev zlib1g-dev fam libdbus-1-dev libdbus-glib-1-dev gobject-introspection libxext-dev libxrender1-dbg colordiff libcairo2-dev libtiff4-dev libpng12-dev libxft-dev libxi-devel
I have the following folders in: /home/mike/gtk
atk-2.1.5
gdk-pixbuf-2.24.1
glib-2.30.1
gtk+-3.2.3
pango-1.29.1
Then:
cd /home/mike/gtk/glib-2.30.1
./configure && make
rm -rf /home/mike/gtk/include/glib.h /home/mike/gtk/include/gmodule.h (glib INSTALL instructions)
repeat for the other folders except without the rm, in the following order:
atk-2.1.5
gdk-pixbuf-2.24.1
pango-1.29.1
gtk+-3.2.3
Before running ./configure for gtk+-3.2.3 enter this in the terminal:
CPPFLAGS="-I/home/mike/gtk/include"
LDFLAGS="-L/home/mike/gtk/lib"
PKG_CONFIG_PATH="/home/mike/gtk/lib/pkgconfig"
export CPPFLAGS LDFLAGS PKG_CONFIG_PATH
LD_LIBRARY_PATH="/home/mike/gtk/lib"
PATH="/home/mike/gtk/bin:$PATH"
export LD_LIBRARY_PATH PATH
export PKG_CONFIG_PATH="/home/mike/gtk/lib/pkgconfig:$PKG_CONFIG_PATH"
I get the these errors when I run make on gtk+-3.2.3:
gdkwindow-x11.c: In function '_gdk_x11_moveresize_handle_event':

You place GTK3's source code in an arbitrary directory (into which you have write permissions). And you run ./configure from there.
You may want to pass the configure scripts (of each package) a common --prefix to override the default of /usr/local/ (this is needed, e.g. with --prefix $HOME/pub, if you cannot write under /usr/ because you don't have root access).
