New description:

 If you run "Pickers" from gtk3-demo the following error is reported
 when you try to choose a file:

 {{{
 GLib-GIO-ERROR **: No GSettings schemas are installed on the system
 }}}


 That's because the
 ```/opt/local/share/glib-2.0/schemas/org.gtk.Settings.FileChooser.gschema.xml```
 has not been compiled: calling ```glib-compile-schemas``` is needed in the
 post-activate stage:


 {{{
 post-activate {
     system "${prefix}/bin/glib-compile-schemas
 ${prefix}/share/glib-2.0/schemas"
 }
 }}}
