Shapely 1.6.4.post2 is available,and only a small adjustment to the current ebuild in portage ( Shapely-1.5.17-r1) to account for the different versioning is needed. Labeling it Shapely-1.6.4_p2.ebuild and using MY_PV=1.6.4.post2 and adjusting the SRC_URI and S to accomidate that (SRC_URI="mirror://pypi/${PN:0:1}/${PN}/${PN}-${MY_PV}.tar.gz" and S="${WORKDIR}/${PN}-${MY_PV}" ) seems to work just fine for an updated ebuild. Reproducible: Always
Updated to 1.6.4
