This is definitely a bug in Debian's LAPACK.


$ nm /usr/lib/libblas/libblas.a | grep xerbla_
0000000000000000 T xerbla_

shows that the symbol xerbla_ is defined the static BLAS library.
Additionally,

$ nm /usr/lib/liblapack.a | grep xerbla_
[...]
0000000000000000 T xerbla_

it is defined in  /usr/lib/liblapack.a. This causes link errors whenever
LAPACK, BLAS are used statically.

/usr/lib/gcc/x86_64-linux-gnu/4.6/../../../../lib/libblas.a(xerbla.o): In
function `xerbla_':
(.text+0x0): multiple definition of `xerbla_'
/usr/lib/gcc/x86_64-linux-gnu/4.6/../../../../lib/liblapack.a(xerbla.o):(.text+0x0):
first defined here
