Here are the last few lines of that output:

check_basic (scipy_base.index_tricks.test_index_tricks.test_grid) ... ok
check_nd (scipy_base.index_tricks.test_index_tricks.test_grid) ... ok
check_gebal (scipy.lib.lapack.test_lapack.test_flapack_complex) ... ok

That certainly seems like must what be happening.  However, I'm using 
gcc 3.4.2 on FC3.  Just to be safe, anyway, I recompiled LAPACK with -O2 
instead of -O3.  No change in the above behavior.
