Compilation problem

[LEROYER Benoit]

I am trying to compile pspp.0.7.8 on redhat Entreprise 6.1 x86_64

I have the following error message :

src/ui/gui/src_ui_gui_psppire-psppire-buttonbox.o: In function
`psppire_buttonbox_set_property':
/usr/local/dist/pspp-0.7.8/src/ui/gui/psppire-buttonbox.c:104:
undefined reference to `gtk_widget_get_realized'
collect2: ld returned 1 exit status
make[2]: *** [src/ui/gui/psppire] Error 1
make[2]: Leaving directory `/usr/local/dist/pspp-0.7.8'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/usr/local/dist/pspp-0.7.8'
make: *** [all] Error 2

Does somebody have an idea?

Greetings,
Benoit
