Strawpants [1] filed a deletion request for shtools-fortran [2]: Dear devs, this package is obsolete as it has been merged in a split package: https://aur.archlinux.org/packages/python-shtools/ which contains both the fortran and python components. So, to avoid confusion, I recommend deleting this package. Kind regards, Roelof [1] https://aur.archlinux.org/account/Strawpants/ [2] https://aur.archlinux.org/pkgbase/shtools-fortran/
