OOPS, Actually, I just downloaded ATLAS and gsl a couple days ago, and lapack
yesterday.

I didn't think the problem was specific to either package as both packages are
having the same problem.  Before I upgraded gcc, all my programs except the one
that used gsl ran fine.  Now they all die with the same error.

That I didn't know.  I downloaded it and build it.  The first time, before
upgrading gcc, it, and it's tests ran fine.  It was only my test program that
used gsl that crashed.  After upgrading gcc to 4.5.3, everything I compile
crashes.  I wonder if it is something in gcc 4.5.3 that is wrong?

Thanks.  It looks like I first have to fix gcc so that the programs I compile
will run properly, and then I'll try th sourc package you made.

Thanks again
