I don't use the mfpic latex package, but I'll show you a sample from  
my setup because it might be helpful.

% include some metapost macro pacages to produce graphs and my custom  
graph sizing.
input graph;
input support/figsize.mp

% put your latex preamble here. Include things like fonts and font  
% They need to work with LaTeX in dvi production mode.

%% end of metapost document. Save as 'angles.mp' and run the following  
commands from the command-line (there may be an easier way with  
TeXShop, I don't know, others will comment).

mpost -tex=latex angles.mp
mptopdf angles.0
mv angles.0 angles.mps
mv angles-0.pdf angles.pdf

and then use angles.pdf with pdflatex as you would do normally.  
pdflatex can also use angles.mps and convert on the fly. This may  
actually be preferred because it prevents multiple inclusion of your  
fonts (not sure about that).

Hope this may help.
