Same results here, if I run Metapost via TeXShop. If you want to use  
LaTeX for your labels, you could:

-- either open the file "metapostwrap" in /Applications/TeXShop/ 
contents/resources, and change this file by replacing the lines:

mpost --interaction=nonstopmode "${filename:r}.mp"

and

mpost  "${filename:r}.mp"

by

mpost --interaction=nonstopmode -tex=latex "${filename:r}.mp"

and

mpost -tex=latex "${filename:r}.mp"

It will force Metapost to run LaTeX for labels. This is the solution  
I'm using.


-- or of course running Metapost through the command line: "mpost - 
tex=latex your_file.mp"...
