Here are the build scripts for gnome these are all set for 2.6.  They 
will download the source and build the package.  You must follow the 
BUILD_ORDER file and build and install each package in order.  It takes 
some time but 2.6 is well worth it.  As with all the build scripts it 
requires the slackbuilds conf file or package to be installed. This will 
allow you to compile with your own optimizations.  If you have problems 
let me know.  And thanks to Robert for all his hard work on his 2.6 
package area. 

Watch the builds for errors and check the package before you install it.

run ldconfig after each package build

Do not build and install the packages while you are using gnome.

upgradepkg will work with all these I didn't have to uninstall anything 
first when I tested it. Some may be new so you will have to use 
installpkg.
