I wanted wiipresent (a handy tool that lets you use a WiiMote as a handy wireless presenter) running on Ubuntu Lucid (10.04). Here's how I did it:

First, I had to download the latest rpm from The Wiipresent site.

Next I needed to install alien to allow me to install the rpm on my debian-based system:
sudo apt-get install alien
sudo alien -i wiipresent-0.7.5.2-1.el5.rf.x86_64.rpm

That worked fine, but wiipresent can't find the wiimote or bluetooth libraries it needs. So first, make sure they're installed:
sudo apt-get install libcwiimote3 libbluetooth3

Then symlink the installed libraries to the place wiipresent is looking for them:
sudo ln -s /usr/lib/libbluetooth.so.3 /usr/lib/libbluetooth.so.2
sudo ln -s /usr/lib/libcwiimote.so.3 /usr/lib/libcwiimote.so.0

Run wiipresent, press 1+2 on your Wiimote, job done!
