how to install on linux

hello

when i try to run the "DraftSight.rpm" on my SUSE 11.3, 64 bit system

i get amessage telling me that "libaudio.so.2" is required by "dassault-systemes-draftsight-2011.2.705-2.i386" while i have the file "/usr/lib64/libaudio.so.2" installed

what is the issue

install instructions are really missing

thanks
