Bug#684127: libopenblas-base: postinst error: alternative libblas.so.3gf can't be slave of libblas.so.3

[Nicolas Noirbent]

Package: libopenblas-base
Version: 0.1.1-5
Severity: important

Dear Maintainer,

libopenblas-base fails to install on my machine at postint with the
following error:

Setting up libopenblas-base (0.1.1-5) ...
update-alternatives: error: alternative libblas.so.3gf can't be slave of libblas.so.3: it is a master alternative

Apparently, libopenblase-base was automatically selected for
installation due to a recent upgrade of libumfpack5.4.0:

# aptitude why libopenblas-base
i   xsane            Depends    libgimp2.0 (>= 2.4.0)
i A libgimp2.0       Recommends gimp-data (<= 2.8.0-z)
i A gimp-data        Recommends gimp
i A gimp             Depends    libgegl-0.2-0 (>= 0.2.0)
i A libgegl-0.2-0    Depends    libumfpack5.4.0 (>= 1:3.4.0)
u A libumfpack5.4.0  Depends    libblas3 | libblas.so.3 | libatlas3-base
C A libopenblas-base Provides   libblas.so.3

Here's what I can gather from the alternatives system wrt libblas.so.3,
if it's of any help:

# update-alternatives --display libblas.so.3gf
libblas.so.3gf - auto mode
  link currently points to /usr/lib/atlas-core2sse3/atlas/libblas.so.3gf
/usr/lib/atlas-core2sse3/atlas/libblas.so.3gf - priority 55
  slave libatlas.so.3gf: /usr/lib/atlas-core2sse3/libatlas.so.3gf
  slave libcblas.so.3gf: /usr/lib/atlas-core2sse3/libcblas.so.3gf
  slave libf77blas.so.3gf: /usr/lib/atlas-core2sse3/libf77blas.so.3gf
  slave liblapack_atlas.so.3gf: /usr/lib/atlas-core2sse3/liblapack_atlas.so.3gf
Current 'best' version is '/usr/lib/atlas-core2sse3/atlas/libblas.so.3gf'.


Edit: I Just found out about http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=659786,
but it would seem the problem is still present for some configurations.

Cheers,
