>Description:
No matter what I do, I can't seem to get the current version of enchant2 to automatically install the `groff` package as a dependency. I've tried cleaning enchant2 multiple times in a couple of ways, but it always just doesn't install groff, which it requires for the build, resulting in:

sh: groff: not found

The Makefile does contain this:

USE_TOOLS+=             autoconf gmake groff pkg-config

...so it should be installing, right? Why doesn't it? I don't understand the recipe format of pkgsrc well enough to understand the issue myself.

This issue can be worked around by installing groff manually, but that isn't really a solution to the core problem.
>How-To-Repeat:
Attempt to build textproc/enchant2 on the current 2026Q1 (commit 69636b6fcb37836ed7abd7335dec2db101a65d0c), and observe the build failing with the above message.
