How to install on Backtrack 5

i downloaded LibO_3.6.3_Linux_x86_install-rpm_en-US.tar.gz
after extraction,there is no DEBS folder…
please help me to install on Backtrack 5

On the download page, http://www.libreoffice.org/download/ , if you want a DEB version, look for the “Change System, Version or Language” link and go from there.
