Linux install "conflicts with file from package filesystem"* on Fedora 18 32-bit

Trying to install V1R3.1 on Fedora 18 32-bit (running in a VirtualBox VM, but that's irrelevant) and I'm getting these warnings from rpm:

# rpm -ivh draftSight.rpm
Preparing...                          ################################# [100%]
    file / from install of dassault-systemes-draftsight-2013.1.56-2.i386 conflicts with file from package filesystem-3.1-2.fc18.i686
    file /usr/bin from install of dassault-systemes-draftsight-2013.1.56-2.i386 conflicts with file from package filesystem-3.1-2.fc18.i686

I could probably override it and go on, sicne many times these sort of warnings are related to permissions on directories and/or files the installer creates. But I figured I'd ask before I go further.

Is this a known issue? Is there a recommended workaround? --force?

Thanks.
