Question for rpm for libGLw.so.1

[Yasushi Okubo]

I am looking for rpm for libGLw.so.1 for WS 3.0 since I can find only 
libGLU.xx files or libGLw.a file. 
This library:  libGLw.so.1 is used by one of applcations at work.  Could 
you advise me which rpm includes this .so file ?
It looks like we have the following XFree86 rpms, but they do not 
include what we want: libGLw.so.1.    Or should I use tar file to force 
installation ?

Thanks,
yasushi
