How to install DraftSight 2015 on Scientific Linux 6.6

Hi, I've a problem with DraftSight 2015 rpm-package installation on SL 6.6 (64 bit). First it lacked a library libaudio.so.2 which was installed. Then it was possible to install DraftSight. But the program can not be executed. Please is there any solution for other Red Hat clones than Fedora, like SL, CentOS...

Thanks very much.
