I installed all pre-reqs including '2:tog-pegasus-libs-2.14.1-7.el7.x86_64', but, I received an error when installing SMI-S. It complained about 'libpegcliutils.so.1'. So I installed the x86 version '2:tog-pegasus-libs-2.14.1-7.el7.i686' and everything is working. Should I make modifications and revert to the x86_64 version?
