An alternative is to use dpkg --derives-from ubuntu - this allows you
to put in conditional logic for Ubuntu builds in debian/rules.
However it does not let you differentiate between Ubuntu releases.

Is there a way to check which boost version is available?  That would
be a much more generic test.  Also the package really should depend on
libboost-dev, not a versioned one, so that it uses the default boost
version in the distro.
