Thanks for the investigation, I just back port the patch for Fedora rawhide now.

Apparently this is because rawhide pango.pc does not add -lglib-2.0
when called with pkgconf --libs:
F-29
$ rpm -q pango
pango-1.42.4-2.fc29.x86_64
$ pkgconf --libs pango
-lpango-1.0 -lgobject-2.0 -lglib-2.0
F-30
$ rpm -q pango
pango-1.43.0-1.fc30.x86_64
$ pkgconf --libs pango
-lpango-1.0
pango-1.43.0-1.fc30.x86_64 pango.pc shows:
----------------------------------
Name: Pango
Description: Internationalized text handling
Version: 1.43.0
Requires.private: glib-2.0 >= 2.38.0, gobject-2.0 >= 2.38.0, fribidi >= 0.19.7, libthai >= 0.1.9, harfbuzz >= 1.4.2, fontconfig >= 2.11.91, freetype2, xrender, xft >= 2.0.0, cairo >= 1.12.10
Libs: -L${libdir} -lpango-1.0
Libs.private: -lm
----------------------------------
So -lglib-2.0 is moved to Requires.private.
I guess this is due to this commit:
https://gitlab.gnome.org/GNOME/pango/commit/86855b6a458fd9b82d246f723a7e3c9cdb37a8a0
It seems to be doing some refactoring (with adding some fallback), and
"requires: gobject_dep," line is deleted.
Currently I am not sure if it is intentional or accidental.I think this commit https://gitlab.gnome.org/GNOME/pango/commit/d0cb6be7431d1a3c711bd45bcf05b34601604037 will revert it back but we need to wait for next upstream pango release.Parag
