[SciPy-user] "Use minimum ordering" message

Simple problem. I'm relatively new to Python, and I'm writing a  
diffusion simulator using the sparse and linsolve modules. Each time I  
solve a matrix, I get the following message:
"Use minimum degree ordering on A'+A."
which results from a printf() in the get_perm_c.c file when a  
permutation matrix is set up.
Questions:
1. Why is this message printed when (I assume) it is not a warning or  
an error? Any output like this slows down the solver when I'm solving  
tens of thousands of matrices.
2. Is there a way in Python to selectively ignore output statements  
like this? I don't want to comment out the source code and recompile.
Thanks,
John
