I think it's a result of the fix for #489253 - the option was
re-enabled but the package was not split.

The particular dependencies I need to have as optional are those
related to ATLAS and Lapack :

libblas.so.3gf , liblapack.so.3gf and libgfortran3 .

The following packages have unmet dependencies:
  python-numpy: Depends: libblas3gf but it is not going to be installed
or libblas.so.3gf or
                         libatlas3gf-base but it is not installable
                Depends: libgfortran3 (>= 4.3) but it is not installable
                Depends: liblapack3gf but it is not installable or
                         liblapack.so.3gf but it is not installable or
                         libatlas3gf-base but it is not installable
E: Broken packages

(This comes from the Emdebian Grip repository which is a filtered
repository and does not include all packages in Debian, just the ones
most suitable for embedded devices. These particular packages are
large and undesirable for embedded targets.)
