It may sound even better if multiple Boost versions were considered,
packaging them in versioned source packages (ie boost-1.34.1,
boost-1.35.0). Respective -dev packages should then be also versioned
and conflicting each other, as the mostly undecorated symlinks there
provided. Having boost-defaults driving the default Boost and Python
versions and the completely undecorated symlinks.

This, for instance, would allow Boost 1.35.0 in lenny while 1.34.1
being the default one. I frankly doubt a full transition to 1.35.0
would happen before the release of lenny.

Ciao,
Domenico
