Atlas is great in the platforms where it's available, however it is not being packaged (for good reasons) anymore. arpack originally used blas for testing and since we are not really linking any version of blas in the package it doesn't make any difference what we use. It seems better idea to use blas for testing since it's faster to build and because this also means we can package arpack without building ATLAS, The resulting package will work with BLAs or ATLAS just the same and in any case the BLAS_LIBS variable can now be overridden to test with atlas if it's so desired. This change doesn't change the package so I think we should leave the PORTVERSION untouched. How-To-Repeat: ARPACK was not being packaged for amd64. I will work with the Atlas maintainer to see how we fix the current atals issues.
State Changed From-To: open->closed Committed, thanks!
