What a lovely example!  When I run this on the command line, it works just fine.
For file z.tex,

latex z
dvips z
ps2pdf z.ps
open z.pdf

But if I

open z.tex

and Typeset it in TexShop (version 2.18-svn) on my Mac OSX 10.6.2, I
get an error:

! Undefined control sequence.
\XC at usec@lor ...\expandafter \c at lor@to at ps #1#2\@@ 
                                                  \else \expandafter \expand...
l.9 \psplot
           [plotpoints=100,algebraic]{-4}{4}{sin(x)}
? 

Hunh?
