I think pkgsrc-2019Q4 has the same problem.

I got around it by down-grading to glib2-2.60.6 from pkgsrc-2019Q3 and changing
   .include "../../devel/py-meson/build.mk"
to
   .include "../../devel/meson/build.mk"

This old version seemed to work well enough for me to build and use modular-xorg-xquartz, but it'd be nice to have the up-to-date pkgsrc version of glib2 working.

cd .../pkgsrc/devel/glib2 && bmake
