Fixed in CVS. This failure appeared when using Fortran BLAS.

Comments:
(i) Have you tried using ATLAS libraries from
       http://www.scipy.org/download/atlasbinaries/linux/
     ?
(ii) Always use ldd on flapack.so to check that system blas/lapack 
libraries are not being used. Also verify the linking command for 
flapack.so and the existence of .a files used in -l.. and that -L..
options are properly ordered so that correct .a files are picked up.
