bluez installation

• bluez-libs-3.1.tar.gz
• bluez-utils-3.1.tar.gz
• bluez-firmware-1.2.tar.gz
• bluez-hcidump-1.31.tar.gz

the first one worked fine.. utils package configuring gave error as below

checking for DBUS... Package dbus-glib-1 was not found in the pkg-config search path.
Perhaps you should add the directory containing `dbus-glib-1.pc'
to the PKG_CONFIG_PATH environment variable
No package 'dbus-glib-1' found
configure: error: dbus-glib > 0.35 is required
