Hey Justin, One thing to note is that a few various python modules, like numpy, really benefit from fortran. While many people using numpy are scientists, many are not and further there are various modules that depend on numpy that non-science folks use. I, for one, care little about where that flag is set, since I have manually set that USE for years now in make.conf. I am simply hoping to make you aware of the fact that there are potential cases that could be easily overlooked. Thanks! Matt -- Matthew W. Summers Gentoo Foundation
