Comment (by breadncup):

 MacPorts was built from source. This happens after building the port.

 While installing gobject-introspection by

 sudo /opt/local/bin/port install gobject-introspection

 the error comes in. If gobject-
 introspection-1.56.1_1.darwin_18.x86_64.tbz2 for macOS Mojave, is there
 any workaround of it?
