I'm not sure of that because I used to do <<apt-get source -b>>
or (when things go wrong in some way) <<dpkg-buildpackage>>, and I
**saw** the download of deb sources I didn't ask, so... there is (?)
some use of build dependencies somewhere 
(more probably with apt-get source -b)

By the way, what are auto-builders ??
What I'm trying to do is to build a memory of the build deps
by annoting a Makefile something like that :

libglib1.2-dev:
        $(COMPILE) libglib1.2-dev
        $(INSTALL) libglib*-dev*.deb

libglib1.2: libglib1.2-dev
        $(COMPILE) libglib1.2
        $(INSTALL) libglib1.2*.deb

libgtk1.2: libglib1.2
        $(COMPILE) libgtk1.2
** I PERFECTLY KNOW THAT THIS IS NOT SUFFICIENT TO REACH
SOMETHING I COULD CALL AN AUTO-BUILDER, ... **

But it is enough to see what difficulties arise when trying to
auto-build some parts of the distribution...
I noted at least to main problems :
a) requesting an apt-get source -b <name> leads to the download of
	- a1 deb source with a different name ...
or	- a2 several deb sources  (obviously with different names :-)

b) building a downloaded debsource leads to
	- b1 (deb) binary with a different name ...
or	- b2 several (deb) binaries with different names (again)

So I wonder what kind of <<protocol>> may exist	in an auto-builder in order
to cope with these issues... 
In other words an auto-builder
should be able (?) to automatically generate the corresponding 
Makefile (in the same way I tried to write one by hand ...)
