To install BOUML you have to extract the tar corresponding to your CPU under '/', so supposing you are in 64b and the tar is in your home dir do cd / ; tar xfz ~/bouml-7.0-gentoo.x86_64.tar.gz
You can launch BOUML in a shell through the command bouml (it is a script placed in /usr/bin), or through the menu corresponding to development
If you need to have it in an other release of Gentoo please ask me indicating which live-dvd iso I have to use
