This is very important because in a 64 bits installation, you will
need some packages in 32 bits version also (rpm -qa will show you
duplicate names because of this). IIRC openmotif21 has 32 bits version

By default, yum installs the default architecture (uname -i) but you
can "yum install compat-libstsdc++-devel.i386" if you need. To see the
architecture of installed packages: rpm -qa --qf
