I'm going to cc debian-boot on this, in the hopes that someone who has
made more udebs than I can help out.

Yes, that's what the documentation said, and I followed the busybox
udeb as an example. Apparently, I should've followed a library as an
example, like libd-i.

So, everyone has said that they have to be build dependencies, which
seems very confusing to me, but I guess that's what we should do. We
can just make our debs a build dependency for cdebconf, since the gtk
module is part of cdebconf.

Well, last I tried my pango udeb didn't compile. I guess I should get
back to making that work.

So, here is the line from the Makefile in the builddir for mklibs, and
it still doesn't look like you need to make the libs a build
dependency, but we'll figure that out.
# Library reduction.
mkdir -p $(TREE)/lib
$(MKLIBS) -v -d $(TREE)/lib `find $(TREE) -type f -perm +0111
-o -name '*.so'`
So, can you send me the output of the makefile, so I can see what
error it puts out? it's possible that your libs are not getting found
by the find command.

Ok, I'll look into finishing my pango deb, assuming my udebs are not
total crap, and then look into atk.
We should probably put out work up somewhere so that other people can
look at it. I could put it up on my d-i site.

Until I hear differently from Tolleff, yes.

you've done as much or more than I have to get these udebs working.
