My results are

	$ /usr/bin/gtk-config --version
	1.2.10
	$

and also

	$ /usr/bin/gtk-config --cflags
	-I/usr/include/gtk-1.2 -I/usr/include/glib-1.2 \\
	-I/usr/lib/glib/include -I/usr/X11R6/include

and
	$ /usr/bin/gtk-config --libs
	-L/usr/lib -L/usr/X11R6/lib -lgtk -lgdk -rdynamic \\
	-lgmodule -lglib -ldl -lXi -lXext -lX11 -lm
$

where I have deliberately added in the \\ to imply that the line is really
wrapped.

And because GTK-1.2 is preinstalled ( rather than RPM'd ) on the latest
release of Mandrake Linux, the next command will give a very predicatable
result.

	$ rpm -q gtkglarea
	package gtk is not installed

Obviously the installation process is relying on some macro set-up by the
rpm.  Any ideas what it is?  Tom, do you have some m4 macro related to gtk
in the area /usr/local/share/aclocal, or anywhere else for that matter?

In the end, I just copied the 2 Makefiles from the previous version of
gtklookat-0.9.1 and the executable compiled and built fine.  However, this
expediency is not the answer. Something seems non-robust. We shouldn't
need to install some new release of GTK just to get OpenVRML working.  I
just can't pin-point it. Maybe we need an m4 macro for those who don't
have got GTK rpm'd on their system.  Maybe I'm just talking through my
hat.

Many Thanks - Damian (McGuckin)
