Debian has provided optimised Atlas libraries, compiled as shared libraries, for over eight years. So not everybody sees this as 'silly'. We set up our R builds to transparently use them. That way you'd get tuned linear algebra as a plug-in -- and the plugin is made possible because of the shared-library build. So not everybody agrees with BDR's resolute statement implying static-only builds if one is concerned about performance. Performance is almost always relative, and often relative to several possibly conflicting baselines.
