LibreOffice 3.4 on Ubuntu 10.4

Ubuntu 10.4 comes with OpenOffice 3.2

I want to have the newest LibreOffice.
Download the installation file from the LibreOffice homepage.
The file is LibO_3.4.3_Linux_x86_install-deb_en-US.tar.gz.
Extract it somewhere.
Read the file /readmes/README_en-US and follow the installation guide therein. Everything goes perfect.
When I started LibreOffice 3.4, it complained that Java runtime cannot be found (I installed the Oracle Java, not the standard way for Ubuntu).
After several ignoring "OK", LibreOffice started, and then via menu Tools/Options/Java the actual Java runtime could be added to the LibreOffice configuration.
LibreOffice when started without complaints.
LibreOffice is installed in /opt/libreoffice3.4.
Very fast, as compared to my Windows system.
