Bug#760282: nmu: scotch_5.1.12b.dfsg-1.2

[Salvatore Bonaccorso <carnil@debian.org>]

Package: release.debian.org

Dear Stable release managers,

I guess this request is quite unfortunate as it affects a rebuild of a
ppackage in stable. Note I'm not the maintainer but we runned into
this problem.

It is tracked in BTS as #748130. The binary packages produced by
src:scotch in wheezy were not (re-)builded at the time picking the
correct default mpi-implementation.

Can the scotch package be binnmu'ed on stable for amd64?

Is

nmu scotch_5.1.12b.dfsg-1.2 . amd64 . -d wheezy . -m "Rebuild to pick the correct mpi-default implementation (Closes: #748130)"

correct?
