AFAICT, the problem here essentially amounts to version skew -- the module you're trying to load into Python 2.5 uses a support library currently built only against 2.4 (as that remains Debian's default for now). This combination evidently happens to work without problems on 32-bit architectures, but fails on 64-bit platforms due to intervening ABI changes.
Anyway, Boost's packager is looking into supporting 2.5 alongside 2.4; you can find the relevant thread starting at http://lists.debian.org/debian-python/2008/02/msg00033.html and continued at http://lists.debian.org/debian-python/2008/03/msg00033.html (yes, really message 33 in both months!) -- Aaron M.
