cannot compile gtk programs

[doobman <bamiller mail ohio net>]

I have recently installed RH 5.2 and installed gnome .099.7 with RPMs.
I have tried installing a slew of programs including x11amp, balsa,
gFTP, and i think thats it.  On every one I try to compile, I get a
similar messege.  This is taken from the ./configure from balsa,
everything is working until it trys to compile a test program:
configure:2102: gcc -o conftest -g -02 -I/usr/X11R6/include
-I/usr/lib/glib/include conftest.c -L/usr/lib -L/usr/X11R6/lib -lgtk
-lgdk -rdynamic -lgmodule -lglib -ldl -lXext -lX11 -lm 1>&5

configure:  failed program was:

#include <gtk/gtk.h>
#include <stdio.h>

int main(){
 return ((gtk_major_version)  || (gtk_minor_version)  ||
(gtk_micro_version));
; return 0; }

I'm verified that these files are in /usr/include/ anything you could
tell me would be an extreme help
