Hi,
While I was trying to install Google Earth 6 I had the same problem. I saw it tried to install redhat-lsb using the command "yum install redhdat-lsb" automatically. So I decided to install redhat-lsb manually by downloading the RPMs, converting them to .tazpkg and installing, but had no success, GE6 seemed not to recognize redhat-lsb even if it was instaled. Somewhere I read redhat-lsb-debuginfo redhat-lsb-graphics redhat-lsb-printing were neccessary, I repeated the proccess without success again.
So I realized that installing GE6 on Slitaz nowadays seems to be impossible, maybe I'm wrong. Anyway what I did is install GE5, which actually works on Slitaz. I found GE5 over the net, in a megaupload link, and downloaded it. I have it saved in case is deleted. Installing GE5 gave me some work too. First I received a message saying:
"I/O error : No such file or directory
setup.data/setup.xml:1: parser error : Document is empty
^
setup.data/setup.xml:1: parser error : Start tag expected, '<' not found"
The solution to that problem can be found here: https://www.linuxquestions.org/questions/slackware-14/google-earth-install-830981/
Once the installation is completed, GE ran but I couldn't read the menus due to a fonts problem. The fonts problem can be solved with this: https://www.google.com/support/forum/p/earth/thread?tid=656ef9a98bc427dd&hl=en
After all now I have Google Earth working on Slitaz, a bit slowly, but Im looking how to solve it.
Sorry for my bad english, I hope this have been helpfull!
