I think I need to start from scratch to get the bluetooth folder in /usr/inlcude. So I downloaded these libraries:
bluez-libs-3.9.tar.gz
bluez-utils-3.9.tar.gz
bluez-firmware-1.2.tar.gz
bluez-hcidump-1.34.tar.gz
bluez-gnome-0.6.tar.gz

and saved them onto my desktop. I have a folder called bluez on my desktop, and I have un-packed the tarballs above.
I am in the terminal trying to install bluez-utils-3.9 by ./configure and I get this error:
configure: error: Bluetooth library is required
Please guide me in my next steps as i am a novice to Linux?
