I've attached a script I use for [h4a].  Maybe you'll find it useful.
It doesn't try to work out dependencies, but instead you need to
provide a good build order.  It sounds like that shouldn't be too much
of a problem for a rather static set of 20 or so packages though.

I invented the term Object-Oriented, and I can tell you I did not have
C++ in mind.

Run this script in your HABS dir to build the named packages inside a
chroot.

The chroot dir consists of two dirs, a pristine chroot (root), and a build
chroot (build).  This script handles both of them.

Options:
-h          This help
-c          Clean the build chroot before building
-x          Update the pristine chroot first (implies -c)
-l <dir>    Location of chroot (default .)
-a <arch>   Architecture to build for i686 or x86_64 (default is local arch)
-b <dir>    Location of your HABS dir (default .)
