Howdy,

You are trying to process the file using pdftex rather than TeX 
+Ghostscript. You can check off the Typeset->TeX and Ghostscript to  
temporarily change to that engine. You can make all files compile that  
way by default via the TeXShop->Preferences->Typesetting->Default  
Script preference. The best way to guarantee that TeXShop chooses the  
correct engine is to put the line

%%!TEX TS-program = latex

for TeX+Ghostscript or

%%!TEX TS-program = pdflatex

for pdflatex processing.

Good Luck,
