[OS X TeX] Feynmp labels

[Donal Day]

My attempt to use the Feynmann diagram drawing package with TexShop  
is only partially successful.

  Following the guidelines at http://osksn2.hep.sci.osaka-u.ac.jp/ 
~taku/osx/feynmp.html I can successfully create diagrams.

However when I attempt to add labels to the lines, they do not show  
up on the resulting figure which is created after processing with  
mpost. But they do show up in the host document - but without the  
figure.


Here is the tex:
%%%%%%%%%%%%
\documentclass[11pt]{article}
\usepackage{graphicx}
	\usepackage{feynmp}
	\newcommand{\minpgap}{20mm}
	\begin{document}
	    \unitlength = 1mm

	  \begin{minipage}{\linewidth}

	\begin{fmffile}{simple5}
		\begin{fmfgraph*}(40,25)
			\fmfleft{i1,i2}
			\fmfright{o1,o2}
% labels on the left hand fermions
			\fmflabel{$e$}{i1}
			\fmflabel{$e'$}{i2}
%			
			\fmf{fermion}{i1,v1,o1}
			\fmf{fermion}{i2,v2,o2}
			\fmf{photon}{v1,v2}
		\end{fmfgraph*}
	\end{fmffile}
       \end{minipage}

	\end{document}
%%%%%%%%%%%%

After typsetting with TexShop (2.09) I go to the terminal and issue  
the command "mpost simple5.mp" which produces a file named  
"simple5.1" which I can view with gv - it contains no labels. I  
rename this file to simple5.ps and typeset my document again.

What appears in the pdf window are the labels and no diagram!

mpost is

MetaPost 0.901 (Web2C 7.5.5)
kpathsea version 3.5.5

I would appreciate some guidance.
