This article will help you to resolve the following error that may be received when opening Scribus on Mac OS X:

The following programs are missing:

Ghostscript: You cannot use EPS images or Print Preview

This error happens when either you don't have Ghostscript installed or it is installed but Scribus doesn't know where it is located. If you have not installed Ghostscript then you will need to do this first. You can download Ghostscript from http://www.linuxfoundation.org/en/OpenPrinting/MacOSX/foomatic. After downloading and installing Ghostscript you can check to see if it is installed by running the following command in Terminal:

/usr/local/bin/gs

If Ghostscript is installed the command line should return the following:

GPL Ghostscript 8.64 (2009-02-03)

*Note: The example above shows the output for Ghostscript version 8.64. The version number will depend on the version that you have installed! To exit the GS> prompt just type quit. (See below.)

quit 

After you have verified that Ghostscript is installed you need to set the path in Scribus's preferences to point at the
location and executable name of Scribus. To do this:

1. First open Scribus
2. Go to Preferences (Scribus->Preferences). *Note: You will have to close the New Document window before being able to select Preferences from the Scribus menu.
3. Go to the External Tools section.
4. Find the PostScript Interpreter section within the External Tools section
5. Type /usr/local/bin/gs in the Name of Executable: field. (See below.)
6. Click OK and now you should be able to use EPS images and Print Preview!
