[Chicken-users] blas egg and atlas patch

[Stu Glaser]

Hi all,

I have changed the blas egg so that it supports ATLAS (Automatically 
Tuned Linear Algebra Software).  Atlas is an efficient implementation of 
BLAS that is automatically tuned for a particular computer.

I have attached the patch (against the eggs svn repository).  Please let 
me know if the formatting is incorrect.
