Thanks for the heads up, Don.  I fixed the file in version 0.1.1.

I also changed the default CBLAS to the one that comes with the GSL.   
Anyone who cares at all about performance will want to configure the  
package to use the best CBLAS on their system.  If this is ATLAS, make  
sure you pass the "-fatlas" argument when you configure the package.
