[SciPy-User] scipy sparse limits

Hi,  I'm trying to use large 10^5x10^5 sparse 
matrices but seem to 
be running up against a scipy limit:

n=10**5, x=sp.rand(n,n,.001) gets 
"ValueError: Trying to generate a random sparse matrix such 
as the product of dimensions is greater than 
2147483647 - this is not supported on this machine"

Does anyone know why limit is there and if I can avoid it? 
(fyi, I'm using a macbook air with
 4gb memory and the enthought distribution)

thanks,
Eric
