How to install Cinnamon from GitHub on Ubuntu 12.04

As a first attempt, a ./configure + make + make install wont work, so I want to share what I've done to make it work. Since it's a development version, I won't install to /usr, but to /opt/cinnamon-dev instead...

These are the steps:


$ sudo mkdir /opt/cinnamon-dev
$ sudo chown $(id -nu).$(id -ng) /opt/cinnamon-dev
$ apt-get build-dep muffin cinnamon

$ cd
$ git clone git://github.com/linuxmint/muffin.git
$ cd muffin
$ autoreconf --force --install
$ ./configure --prefix=/opt/cinnamon-dev
$ make
$ make install

$ cd
$ git clone git://github.com/linuxmint/Cinnamon.git
$ cd Cinnamon
$ autoreconf --install --force
$ aclocal
$ intltoolize --force
$ env PKG_CONFIG_PATH=/opt/cinnamon-dev/lib/pkgconfig CFLAGS="-w" ./configure --prefix=/opt/cinnamon-dev
$ make
$ make install

# FAIL!

$ cd files/
$ mkdir -p opt/cinnamon-dev
$ mv usr opt/cinnamon-dev/
$ mv etc/ opt/cinnamon-dev/
$ cd ..
$ make install

# Now works!

The ugly "moves" after the fails are needed because I think some paths are hardcoded, and the process that copies the files from the "files/" directory ignores the "--prefix" configured.
