Bug#588175: liblapack-dev: please change the order of the dependencies

[Bernd Zeimetz]

Package: liblapack-dev
Version: 3.2.1-8
Severity: important

Currently liblapack-dev depends on

libatlas-base-dev | libblas-dev | libblas-3gf.so

which results in libatlas-base-dev being installed by default from
sbuild as it is the first in the list.
This again results in a hard coded dependency on atlas, as
libblas-3gf.so is provided from atlas then, and dpkg-shlibdeps decides
that the atlas base package is necessary to fulfill that dependency.
Actually I'm not sure if that is another bug in atlas, but for now the
best thing to avoid the unnecessary dependency on atlas would be to
change the build-dependency of liblapack-dev to

libblas-dev | libatlas-base-dev | libblas-3gf.so

The other workaround for packages build-depending on liblapack-dev
is to build-depend on libblas-dev before liblapack-dev first, then
sbuild is happy and does not install libatlas-base-dev.

Also see #403246 for details.

Cheers,

Bernd
