[Lapack] widespread failures in dgd.out

Guys,

If I build lapack 3.3.1 or 3.4.0 from the tarfiles (with f77blas), and then
do a "make double" in TESTING/, then when I scope dgd.out I see:

 DXV drivers:    200 out of   5000 tests failed to pass the threshold


When I look at these errors, many are of size 10^3, which often doesn't mean
error at all, but quite a few are more like 10^7, which usually indicates
a real error.  

Is this behavior expected and what is the explanation?

Many thanks,
Clint
