MarsSeed [1] filed a deletion request for python2-behave-git [2]: Unneeded, orphaned Python 2 VCS package, last updated in 2015.
Cannot be built because of missing Py2 dependency. Nothing requires this package so I recommend deletion. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python2-behave-git/
