Yes, first and most importantly do

   # apt-get install pkg-config

which is lacking by your printout (the line second to last). This 
explains most of the present problems, since it provides a mechanism
to out locations of libraries, and then to configure source code that
depends on these libraries.

I did the following to check your prospects, likewise an Debian Etch
system, but this machine is only slowly getting to the expanded stage
where my Debian Sarge is at.

$ mkdir /tmp/blind

$ cd /tmp/bluez-libs-3.12
$ ./configure --prefix=/tmp/blind

$ make              # No errors should occur
$ make install      # You can perform a dry run using "make -n install",
		    # read the output, and se where things go.
		    # Somewhat technical output, though.

$ cd ../bluez-utils-3.12
$ ./configure --prefix=/tmp/blind --with-bluez=/tmp/blind
$ make 

This aborts with an error for device.c complaining about
LMP_PAUSE_ENC, LMP_NFLUSH_PKTS, and LMP_LSTO. The Bluez spacialist
have to take over if your machine gets stuck here, since I only
use Bluez-utils 2.25 and 3.7. But at least, when you can reach this
stage the original hurdle has been overcome, since you have a working
copy of libbluetooth2.

Just a reminder, this.so is a dynamic/shared library, whereas that.a
is a static library. Most users will never need to tell them apart.
You will soon learn when progressing further on the road of tailoring
your own software.

Best regards,	Mats E A
