acxz [1] filed an orphan request for orocos-kdl [2]: This package depends on `eigen3` which should be changed to `eigen` due to recent official repo changes. The maintainer has not updated the package and as such I would be willing to maintain this package. [1] https://aur.archlinux.org/account/acxz/ [2] https://aur.archlinux.org/pkgbase/orocos-kdl/
