>Description:

	On a Darwin 24.6 Mac ('Sequoia', Apple silicon), devel/pango
	fails to link during a pkg_rolling-replace run, with a warning
	indicating version skew with an unnamed library:

*** Error code 1


	I rebuilt glib and its friends, to no avail. The web has
	little on 'pango_font_color_get_type'.

	
>How-To-Repeat:

	Attempt to build devel/pango on a Mac with an older pango
	version	installed, e.g. with pkg_rolling-replace(1).

	
>Fix:

	Tell the meson/ninja clown cart not to look at libarries under
	PREFIX, I guess...

	As a workaround, removing the installed pango package
	('pkg_delete -ff pango') will let the build complete.
