I'm a MacOS X user and use a package manager to build lapack/blas ... usually I 
just use the lapack/blas that comes with MacOS X.

I looked over the lapack sources from netlib, but don't see why you'd get names 
as you did.

What OS are you running?

Where did you get your lapack, and how did you build it?
