I have been repackaging the rpm binaries from LibreOffice with the scripts from SlackBuilds.org (slightly modified by me). This is the one I used for RC3, which probably needs only 2 lines changed for the final release. I can't make the changes until I can get the new rpms though, which I should have tomorrow, with any luck. In case anyone wants to go for it, here is the script plus additional needed stuff (attached) and the 2 lines that you need to fix:
In libreoffice.SlackBuild, change the following 2 lines to the correct version number:
VERSION="3.3.0rc4"(I presume "3.3.0")
mv desktop-integration/libreoffice3.3-freedesktop-menus-3.3-6.noarch.rpm .(you need to explode the package and check inside the desktop-integration directory to find this)
Optionally, you could fix the version number and download links in the libreoffice.info file, but I don't really see the point.
