Compile xcb-proto, libxcb, fontcacheproto

cd /wakes/xorg-2/src/extras
tar -xjf xcb-proto-1.0.tar.bz2
cd xcb-proto-1.0
./configure --prefix=/wakes/xorg-2/build
make
make install

cd /wakes/xorg-2/src/extras
tar -xjf libxcb-1.0.tar.bz2
cd libxcb-1.0
export PKG_CONFIG_PATH=/wakes/xorg-2/build/lib/pkgconfig
./configure --prefix=/wakes/xorg-2/build
make
make install

cd /wakes/xorg-2/src/proto
tar -xjf fontcacheproto-X11R7.0-0.1.2.tar.bz2
cd fontcacheproto-X11R7.0-0.1.2
./configure --prefix=/wakes/xorg-2/build
make
make install

if it fails because of ft_isdigit, just restart the build script.

Using build-from-tarballs.sh script (maybe deprecated....):

./build-from-tarballs.sh -e -bz2 /path/to/xorg.freedesktop.org/archive/X11R7.2/src/everything/

Short version:
1. download everything from http://xorg.freedesktop.org/archive/X11R7.3/src/everything/
2. download damageproto 1.1 separately (http://xorg.freedesktop.org/archive/individual/proto/damageproto-1.1.0.tar.bz2)
3. download latest Mesa3D and unpack it somewhere near
4. download the build-from-tarballs.sh script (http://gitweb.freedesktop.org/?p=xorg/util/modular.git;a=blob_plain;f=build-from-tarballs.sh)
5. assuming you're installing to /usr/X11R7.3:
- export PATH=/usr/X11R7.3/bin:$PATH
- export PKG_CONFIG_PATH=/usr/X11R7.3/lib/pkgconfig:$PKG_CONFIG_PATH

6. ./build-from-tarballs.sh -m PATH_TO_MESA -n -bz2 -e /usr/X11R7.3
