Bug#656039: liblapack3: Provides liblapack.so.3gf virtual package without registering corresponding alternative

[Jonathan Nieder]

Package: liblapack3
Version: 3.4.0-1~exp1
Severity: serious
Justification: breaks rdeps

Hi,

When I try to use "import numpy" from python, I get the following
error[1]:

	ImportError: liblapack.so.3gf: cannot open shared object file: No such file or directory

Indeed, there is no liblapack.so.3gf in /usr/lib or any of its
subdirectories.  This shouldn't be possible because the python-numpy
package[2] depends on liblapack3gf | liblapack.so.3gf | libatlas3gf-base.

Luckily this only affects the liblapack packaging in experimental.

Known problem?
Jonathan
