with these news, i need to understand how boost debian package needs
to move.

currently unstable has boost 1.33.0, which would be ready for testing if
it did not depend on gcc >= 4.0.2-3.  my understanding is that gcc-4.0,
as it is now, will never enter testing, so neither current boost will.

once libstdc++ gets back to new allocator, boost will probably need
a change of name and new dependency version on gcc 4.0 (and a rebuild
of all of its rdepends, like kdeedu). in this case i would push boost
1.33.1, due to be released in few days, and take this wave of rdepends

my issues are with current kdeedu 4:3.4.2-2.1 depending on boost 1.33.0
and already in testing, while boost 1.33.0 is not, and with undergoing
c++ transition, which i honestly did not follow. am i missing anything
here? thank you.
