OK, mfpic probably assumes metafont rather than metapost, right? I  
use metapost, and my experience with mf is very limited. I prefer to  
have external files anyway, so I see having external files as a benefit.

If you call metapost as:
     mpost -tex=latex file.mp
then the latex format will be used for setting text (so you can use  
whatever you're (well, I'm at least) used to).

A small sample may help others,


%% begin file
input graph;

def GraphWidth = (106mm) enddef ;
def GraphHeight = (68mm) enddef ;


prologues := 2 ;

beginfig(0) ;
	numeric scalefactor; scalefactor := 1.2cm;
	numeric theangle;    theangle := -32;
	pair pntone, pnttwo ;
	pntone := (0,scalefactor); pnttwo := pntone rotated theangle;
	draw (-1.1*scalefactor,0) -- (1.1*scalefactor,0)
		withpen pencircle scaled 0.5pt withcolor black;
	draw (0,-1.1*scalefactor) -- (0,1.1*scalefactor)
		withpen pencircle scaled 0.5pt withcolor black;
	drawarrow (0, -0.5*scalefactor) -- (0,0.5*scalefactor)
		withpen pencircle scaled 1.5pt withcolor black;
	draw origin -- (0,1.1*scalefactor) rotated theangle withpen  
pencircle scaled 0.5pt withcolor black;
	drawarrow for i=0 step -4 until theangle+4:
		(pntone rotated i) ..
	endfor pnttwo withpen pencircle scaled 0.5pt withcolor black;
	draw btex $z$ etex shifted (-2.5mm, 11mm) ;
	draw btex $\mathbf{p}$ etex shifted (1mm, -3mm);
	draw btex $\vartheta'$ etex rotated 10 shifted (0,8mm) rotated -10;
endfig ;
