Comment (by pearu):

 No probelem with renaming.

 Here follows a "fix" that should be inserted to linalg/setup.py file:

 config.add_library('pyxerbla', sources=['python_xerbla.c'])
 lapack_lib['libraries'].append('pyxerbla') # one can also try .insert(0,
 'pyxerbla')

 I have tested it and it does not work if xerbla is already included in the
 lapack library.
 With gnu compiler it does have no effect and with MSVC, the linker fails
 because
 of multiple definitions of the same symbol.

 I sincerily hope that you will be more succesful.

 Otherwise, the fix of the issue means that lapack libraries need to be
 changed.
 This is no probelm if users build their own lapack library and then we can
 give detailed instructions for how to do it. But the problem will be with
 most users
 who use system wide lapack libraries.
