Yes, I checked it:

[neteler at wfpovo238 r3.showdspf]$ locate Xm/Xm.h
/usr/X11R6/include/Xm/Xm.h
[neteler at wfpovo238 r3.showdspf]$ head /usr/X11R6/include/Xm/Xm.h

Ah, found it, it was confused by '-I'. So the Makefile is not
right. After fixing that
 GLXContext
is not found. Maybe
 /usr/X11R6/include/GL/glx.h
must be included. I have added that to now 5.3's kns_defines.h file.

Tested ok on redhat9 and Mandrake 10.
