Go to a suitable directory on your machine. I will use <nogo> as a directory in these examples. Then check out a copy of Fuego (in the example, svn revision 1937) with
svn co -r 1937 https://fuego.svn.sourceforge.net/svnroot/fuego/trunk fuego
Don't forget the /trunk part. Follow the build instructions. It is easiest to use the setup-build.sh script in fuego.
For more information on Fuego see here.
For information on downloading and installing GoGui see here.
