Comment:
So, I ended up finding  a package that used `opam install` within it's template and applied that method to the wyrd package. The new template looks like this:
```
# Template file for 'wyrd'
pkgname=wyrd
version=1.5.3
revision=1
build_style=gnu-configure
#configure_args=""
#make_build_args=""
#make_install_args=""
hostmakedepends="ocaml camlp5 opam base-devel"
makedepends="ncurses-devel"
depends="remind"
conf_files="/etc/wyrdrc"
short_desc="Ncurses front-end to Remind"
maintainer="Barbaross <cullenrss@gmail.com>"
license="GPL-2.0-or-later"
homepage="https://gitlab.com/wyrd-calendar/wyrd"
distfiles="${homepage}/-/archive/${version}/wyrd-${version}.tar.gz"
checksum=1d7936dd10b795a17bbce06ae14079eb36120f26fd7bd27b522f8df5196790e7

pre_configure() {
	./prep-devtree.sh
}

pre_build() {
	opam init -y --compiler=ocaml-system --disable-sandboxing
	eval $(opam env)
	opam install -y curses
}
```

The issue now however is that during `opam install -y curses`, an error occurs in which one of the dependencies fails to get installed and therefore breaks the command. See [here](https://github.com/ocaml/opam-repository/issues/19600). There seems to be debate on whether the fix should come from either Void or the maintainer of the ocaml dependency. A Void maintainer has made a firm stance against fixing the issue in `pkg-config` ([source](https://github.com/void-linux/void-packages/pull/32988)), so it seems the fix needs to come from opam, where an [issue has already been reported](https://github.com/ocaml/opam-repository/issues/19600).

So it seems I'm back to square one.  An [AUR package](https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=ocaml-curses) managed to get it working through dune, but again, I'm unsure of how to approach this for Void's xbps packaging.
