[pstricks] Help with a Phase Diagram

[Dougherty, Michael]

Sorry for what is likely a stupid question, but Herbert, when I latex the file you sent I get lots of errors, the first being 
! LaTeX Error: Unknown option `dvipsnames' for package `pstricks'.
Then it sayes \definecolor is an Undefined control sequence.
Then with the colors all undefined they get spit out as text on the diagram, but the phase diagram itself looks OK.

So I guess I'm missing something that gives me the dvipsnames option for pstricks?

I'm on a Fedora Core 2 installation of Linux.

Though I'm not working on any such thing right now, I don't like when I can't compile the examples (generously) given on the list.  Any help appreciated.

you can stretch the image with \psscalebox
