Jekyl on macOS High Sierra

POSIX at heart, macOS serves my LAN for SCP, HTTP and git.

Mojave (macOS 10.14) does not support my MacBook, and new macOS releases typically break MacPorts for up to 6 months.
By dropping 32-bit support, Mojave is likely to be worse.

On Macs, SmartGit looks for SSH key password in the Keychain

As usual, Jekyll for macOS depends on Ruby
Jekyll on macOS using MacPorts
Jekyll GitHub Pages on macOS

…but macOS Ruby is/was another story…

macOS High Sierra /user/bin/ruby is version 2.3.7p456
Perhaps that should suffice, but mixing Jekyl gems with any for macOS seems messy,
and MacPorts has ruby version 2.5.3p105 which installed as /opt/local/bin/ruby2.5

HomeBrew is arguably a better fit for GitHub,
but MacPorts has provided me packages since before HomeBrew launched.
This page describes setting ruby25 as ruby:
$ sudo port select --set ruby ruby25

click for `rbenv` digression

If that scrogs stuff depending on /user/bin/ruby behavior, then
another tool, `rbenv`, only affects shells with a modified `$PATH`,
which could be set in my `g` alias that goes to local GitHub Pages repository.
