I believe you can safely ignore these errors. The comparison is
on line 510 of eigen/test.c:

gsl_test_abs (gsl_complex_abs(vivj), 0.0, N * GSL_DBL_EPSILON, 
              "%s, orthogonal(%d,%d), %s", desc, i, j, desc2);

which you could change to:

gsl_test_abs (gsl_complex_abs(vivj), 0.0, 10.0 * N * GSL_DBL_EPSILON, 
              "%s, orthogonal(%d,%d), %s", desc, i, j, desc2);

to possibly fix the error.
