Thank you for providing the above explanations.
Actually, configure fails for it is looking for GTK and it is not
installed on my system.

------------------------------
checking for gtk-config... no
checking for GTK - version >= 1.2.0... no
*** The gtk-config script installed by GTK could not be found
*** If GTK was installed in PREFIX, make sure PREFIX/bin is in
*** your path, or set the GTK_CONFIG environment variable to the
*** full path to gtk-config.
configure: error: Cannot find GTK: Is gtk-config in path?
-------------------------------

Is there any mean to avoid this error ?
Looking at configure script, GTK seems to be optional, but I did not
find how to disable it in configure ?

./configure --disable-gtktest

did not make it.
