I am no longer sure myself. Debian & thus Ubuntu seem to be only
packaging the BLAS part of OpenBLAS for the libblas.so symlink and
uses the reference implementation of lapack for the liblapack.so
symlink.

I observed a sparse leastsqr bug when linking scipy against the full
OpenBLAS under OSX that I could not reproduce under with the openblas
+ lapack combo shipped Ubuntu so there might be a difference. But that
could also be caused by a version / platform discrepancy between my
two setups.
