[opendx-users] libXm.so.2 missing

[Valmor de Almeida]

 Hello list,

 I am trying to install opendx-4.1.1-1.i386.rpm on 
 a RH 7 laptop. I first intalled

 sgi-opengl-1.2.1-1.i386.rpm  and
 libcdf-2.7-1.i386.rpm

 The error message is as follows

error: failed dependencies:
        libXm.so.2 is needed by opendx-4.1.1-1

 I searched for libXm in my system and this is
 all I have

/usr/X11R6/lib/libXmu.so.6
/usr/X11R6/lib/libXmu.so.6.1
/usr/X11R6/lib/libXmu.a
/usr/X11R6/lib/libXmu.so

 Does anybody know where I could get libXm?

 Thanks,
