We more or less did, but there was no resolution and the problem still persists (at least for me).  Thus, I am trying to resurrect the thread so that we can solve the problem.

Just for reference, are your MacOS builds on systems with SIP enabled?  Can you export LD_LIBRARY_PATH into your shell environment?  (I cannot with SIP enabled.)

I think you are correct that pkgsrc uses LD_LIBRARY_PATH when needed.  However, SIP removes that from the environment, so it does not help in situations like this.  I believe that is why I can build these packages with SIP disabled, but not when enabled.  

It may, however, be a bit more complicated.  The glib2 build process is described at https://developer.gnome.org/glib/stable/glib-building.html.  The upstream intention seems to be the following two commands:

	meson _build
	ninja -C _build

When I do the following:

	cd devel/glib2
	bmake extract
	cd work/glib-2.62.3
	meson _build
	ninja -C _build

Everything (including plugin-resources.c, see error below) completes without error.  However, building the same with pkgsrc yields the following error:

[864/1124] Generating plugin-resources.c with a custom command.

  Reason: image not found
ninja: build stopped: subcommand failed.
*** Error code 1

Thus, pkgsrc is doing something different and I certainly am having trouble figuring out what.

I would greatly appreciate help with this, as the same problem seems to break anything that is using meson in this way.

Thank you very much.

Cheers,
