When starting a new ubuntu gutsy system for development it is very recommend to have the latest sources of the program you want to develop. Of course. Usually you download it, unpack it, read the Readme, where you can might find some dependencies. Might not. Afterwards you do a './configure' and has to install other missing packages. For Elisa-Developement it is very usefull to use the latest svn sources of elisa itself and of course of pigment. And using Ubuntu Gutsy, there is a faster way than try-and-error on installing the missing dependencies.
If you want to have the latest pigment, you simply do:
sudo apt-get build-dep libpigment0.3-1
After that you can do a normal checkout and do an './autogen.sh; make' to compile it. It is also very usefull to use the subshell-script pgm-uninstalled in misc. It is setting al the variables you need for your elisa-enviroment and it is not crushing any installed pigment.
To have the latest elisa running, you have to install some packages. To make it easier, I made this one-line command that installs everything necessary to run elisa on an ubuntu gutsy:
sudo aptitude install diffstat gawk python-setuptools python-twisted-bin python-twisted-core python-zopeinterface quilt python-imaging python-twisted-web python-pysqlite2
