Problem Installing Sparkline Extension

I am getting an error while trying to install a free extension called EuroOffice Sparkline. The extension is listed in the OpenOffice extension catalog and also here:

I tried installing it in both LibreOffice Portable 3.5.0 and OpenOffice Portable 3.2. I get very similar error messages that I am including below. My system is a Win XP SP3 with 4GB RAM.
