Need a clue to solve a Boost inconsistency under Angstrom

I'm attempting to build OSSIE using the Bitbake build system for the
BeagleBoard. I've successfully built the Angstrom x11-image
(local.conf lists DISTRO = "angstrom-2008.1") on my cross-build system
(running Debian Lenny updated a week ago), so I trust the basic sanity
of my OE toolchain and the basic Angstrom build.

I've followed the instructions at "Getting started with Embedded SDR"
(http://www.opensdr.com/node/7), with adaptations that seem reasonable
for the latest bitbake, mainly replacing ${OEDIR} with ${OETREE}. (I
notice those instructions date from 2008, so there may be something
else obsolete I'm doing...) I have also compared them to the Overo
build instructions, and I don't see any obvious incompatibilities.

The OSSIE version I'm getting from the SVN repo at
https://svn.geekisp.com/opensdr/OE/ossie_collection is 0.7.0.0, tagged
as ossie-cf-0.0.0+svnr380-r2.

When I try to bitbake a console-image with the OSSIE collection
included, I get an error compiling the OSSIE CF, which seems to be an
incompatibility with the Boost package, version 1_36_0, that is pulled
in by bitbake. The error is listed below:
