Comment 37 for bug 863154

*Gimp 2.7+Git compilation info :

 I advice this script : http://blog.zanshine.com/blog/stephane-richard/2011-05-10/cutting-edge-gimp-in-latest-ubuntu/

Here I did local change to the script to make it cleaner :
l.52
opt_dir="/opt"
( to build in opt and keep 2.6 , I also create a 'gimp' folder with 777 right in this /opt/ folder )

l.55
src_dir="$HOME/source-to-compile/gimp-razor/"
(the place I keep the source )

l.186
sudo make install || exit_with "while executing 'make install' for $name"
( I add 'sudo' )

Then I run the script and it work alone automagically. Same to update.
To launch Gimp : it's in a 'bin' folder inside /opt/gimp ... easy to create a launcher.
