External Software Requirements

External Tools required to work with SAS

Some SAS tasks require the use of some external tools. The following Table provides the list of these tools.

Tool	Latest tested version	Web page	Other requirements
ds9	5.5.1	ds9 web page	xpa 2.1.9 (same ds9 web page)
Grace	5.1.20	Grace web page	To build binaries, it needs Lesstif
Heasoft	6.6.1	Heasoft web page	Suffcient to download binaries.

Required Perl configuration

Some SAS tasks are perl scripts. These tasks require that perl be installed as /usr/local/bin/perl, either as a real existing binary or as a soft link to any other perl binary, typically /usr/bin/perl.

Assuming you have already some perl binary as /usr/bin/perl, to create a soft link /usr/local/bin/perl, you may proceed as follows:
ln -s /usr/bin/perl /usr/local/bin/perl

X11 on Mac OS X

To work with SAS on Mac OS X we need to have the X Windows or X11 (a.k.a X11R6) software installed. This software is included by default on any Mac OS X installation DVD under the subdirectory of Optional Installs, under Applications. Alternately you may install it from the Fink repository of Mac OS X software, on this link. If you choose this option, you must deinstall the X11 software from Apple or at least move it away of /usr/X11R6. Refer to this document for details.
