Problems with undefined reference errors

[Bill Baker <bill_chris@xxxxxxxxxxxxx>]

Ever since I upgraded to Red Hat 9, I have been having problems
compiling programs.  I tried searching the web, but have had no luck so
far.  I have a custom build of XFree86 (4.3.0-3) installed that I built
from the source RPM under Red Hat 8.0, however this problem did not
start showing up until I upgraded to Red Hat 9.  The problem is that I
keep getting "undefined reference" errors from certain X libraries. 
Here is an example of a small C program I tried to compile just today
under gcc-3.2.2-5:

#include <X11/extensions/XTest.h>
#include <X11/keysym.h>

int main(void)
{
        Display* disp = XOpenDisplay(NULL);
        if (disp == NULL) return 1;
        XTestFakeKeyEvent(disp, XKeysymToKeycode(disp, XK_Num_Lock),
True,CurrentTime);
        XTestFakeKeyEvent(disp, XKeysymToKeycode(disp, XK_Num_Lock),
False,CurrentTime );
        XCloseDisplay(disp);
        return 0;
}

The command I used to compile it was:

gcc -I/usr/X11R6/include -L/usr/X11R6/lib -o setnumlock numlock.c -lX11
-lXtst

And the output was:

Any ideas about what's going on?
