This is the pkgsrc-based package manager I use on macOS. It's simple and has the packages I need.
Note that Pkgsrc is a NetBSD-derived project.
The Joyent folks leveraged it to allow their customers, who were perhaps not as familiar with Solaris/SmartOS, a larger pool of packages. Pkgsrc was running on Solaris before Joyent, Joyent built on top of it.
