Please add the new version to the tree. https://github.com/zhaozg/lua-openssl/releases
I did a version bump to 0.7.3 https://metagit.org/gentoo/overlay/commit/d9b0033b88f24e78c2d887c3d279cc6322a2d83b As soon as it's tested I'll raise a PR to the gentoo repo.
I think this one can be closed because 0.7.3 is now merged into master.
