Pango generates "get_type" functions from enums, using gnome.mkenums() in meson.build.

This enum is PangoFontColor in pango-font.h which was added recently in version 1.57.

I think the build system is linking with the previous libpango.dylib -- the one in /opt/local/lib, not the libpango it just built in devel/pango/work.

This will tell you what libpango.dylib the Pango-1.0 executable is loading (one line):

    DYLD_PRINT_LIBRARIES=1 /opt/local/var/obj/pkgsrc/devel/pango/work/pango-1.57.0/output/*/Pango-1.0 2>&1| grep libpango

It should print the libpango.dylib in devel/pango/work.
