The build can just be renamed, although the patch for setup.py has changed slightly
Created attachment 76052 [details, diff] New patch to setup.py
The old 0.7.1 ebuild also contains a typo: pkg_postinst() { einfo "Installing dev-python/celementree may enhance performance." } It should be dev-python/celementtree with 2 t's
In Portage. Thanks.
