Dep-waits for libgnomemm2.6

[Deng Xiyue <manphiz-guest@users.alioth.debian.org>]

Hi Release Team:

As libgnome is built but not yet uploaded on alpha, powerpc and sparc
(which I should've noticed if not looking at a wrong page), plus
libgnomemm2.6 doesn't has versioned depend on libgnome in sid, a
dep-wait might be required to avoid FTBFS:

dw libgnomemm2.6_2.24.0-2 . alpha powerpc sparc . -m "libgnome2-dev (>= 2.24.1-2)"

Thanks.

Regards,
