I’m not sure if it will work, if you decide to try it, share your results with the community. Regarding the installation, I think you need to have the make and install commands to be able to install the package. In order to do this, follow this guide to load the packages into the opkg http://alextgalileo.altervista.org/package-repo-configuration-instructions.html , then follow this other one to install all the necessary packages http://alextgalileo.altervista.org/blog/installing-development-tools-onto-official-linux-image/ . Once this is done, you need to search for the package that you are looking for the i586 architecture, copy it into your SD card, extract it and then use the make, install or configure to install the package. This is the procedure I’d try to install it. Another thing you can consider is using one of the modules for Bluetooth included in the first link I've sent you, like BlueZ. I hope you find this helpful.
