I don't have the .deb but here is the compiled .so plugin file.

Just put it in /home/user/.purple/plugins/pidgin-n800-led-plugin.so
Then Pidgin>Tools>Plugins>[x] N800 LED plugin>Configure Plugin
I'm not sure if you need any other files.

I've been having major file hosting problems so I'm just going to attach the file, sorry. Just download the .zip and extract the file.

P.S. Addison, yes I have been extremely overwhelmed as of late. I also did a reinstall of Fedora and forgot to add my gtalk account to pidgin. Sorry.
