 We want ports that require GLib to be able to use either `glib2` or
 `glib2-devel`. The “`path:lib/pkgconfig/glib-2.0.pc:glib2`” depspec means
 that the presence of the file `${prefix}/lib/pkgconfig/glib-2.0.pc`
 satisfies the dependency, otherwise install port `glib2`. So a user with
 `glib2-devel` installed would not have to install `glib2`.
