Can't install port that is visible on macports.org [Macports]

Question

I've been trying to get some of my packages from Homebrew moved to Macports recently. One such package was the Crystal programming language. Unfortunately, sudo port install crystal doesn't work:

$ sudo port install crystal
Error: Port crystal not found

Likewise, port info and port search yield no info about the Crystal language:

$ port info crystal
Error: Port crystal not found
$ port search crystal
crystfel @0.6.1_6 (science)
    A suite of programs for processing serial crystallography data

gnome-chemistry-utils @0.14.17 (gnome, science, chemistry)
    This package provides a set of Gtk3-based applications for drawing and viewing molecules, crystals and spectra.

gpp4 @1.3.1_1 (science)
    macromolecular crystallography library

xcrysden @1.5.60_2 (science)
    X-windows CRYstalline Structures and DENsities

Found 4 ports.

Yet, when I search macports.org for crystal, I see it:

Here's the search URL.

What's going on? Why can't I install Crystal, yet I can see it on the website?

Try updating Mac Ports using the command sudo port selfupdate. You can read more about updating and installing Mac Ports here.
