I guess that information is about the runtime libraries you have? I said
before that the terminal Denemo prints out the compile time headers it
was built with, I see that's wrong. But 
denemo --version
at the terminal does print this out (sorry for wrong information).

you would need to examine the source code that Ubuntu should provide for
that - Ubuntu have in the past created modified versions of Denemo that
don't work.

You built from git here, so this code should be present in the toplevel
header include/denemo.h

#if ((GTK_MAJOR_VERSION == 3) && (GTK_MINOR_VERSION >= 10))
#define FAKE_TOOLTIPS 1
#endif

#ifdef FAKE_TOOLTIPS
#define FAKE_TOOLTIPS_MASK  GDK_ENTER_NOTIFY_MASK //GDK_POINTER_MOTION_MASK
#define FAKE_TOOLTIPS_SIGNAL "enter-notify-event" //"motion-notify-event"
#define fake_put_tooltip(w, t) {gchar *tip = 
g_strdup(t);g_object_set_data(G_OBJECT(w), "tooltip", 
(gpointer)tip);gtk_widget_add_events (w, 
FAKE_TOOLTIPS_MASK);g_signal_connect_after (w, "destroy", 
G_CALLBACK(free_tooltip), tip);g_signal_connect (w, FAKE_TOOLTIPS_SIGNAL, 
G_CALLBACK (show_tooltip), tip);}
#define denemo_widget_set_tooltip_text(w, t) {gtk_widget_add_events (w, 
FAKE_TOOLTIPS_MASK);g_signal_connect (w, FAKE_TOOLTIPS_SIGNAL, G_CALLBACK 
(show_tooltip), g_strdup(t));}
#define gtk_widget_set_tooltip_markup(w, t) fake_put_tooltip(w, t)
#define gtk_widget_set_tooltip_text(w, t) fake_put_tooltip(w, t)
#define gtk_widget_get_tooltip_text(w) g_object_get_data (G_OBJECT(w), 
"tooltip")

#else
#define denemo_widget_set_tooltip_text gtk_widget_set_tooltip_text
#endif


what this should do is replace all the calls to set tooltips on Denemo's
widgets with calls to attach the tooltip as (private-to-denemo) data to
the widget. At the moment not very much is done with it I think, but
eventually I hope to get a help-system revived.
 So on my builds I get this

denemo --version

GNU Denemo version 2.0.13
Gtk versions runtime: 3.14.5, compiled against: 3.14.5, 

and I don't get any tooltips showing.

If you can modify denemo.h so the first bit goes thus

#if ((GTK_MAJOR_VERSION == 3) && (GTK_MINOR_VERSION >= 10))
#error "test of Gtk version failed"
#endif

then your compile should stop with that message...

yes, I'm not sure what is happening with your build. If you aren't
familiar with the C syntax I can suggest stuff to probe the problem.
