metapost output again



OK, I've been trying to figure out what is wrong, so I made a very simple diagram file, with only a line and a text item. I used dia 0.92.2 to output to metapost, and dia 0.94, the version can be converted to mps with mpost, but the version using 0.94, can't. Examination of the mp files show their differences:

################### VERSION 0.92 ######################
% Metapost TeX macro
% Title: C:\Documents and Settings\cali\Desktop\diagrams\test.dia
% Creator: Dia v0.92

beginfig(1); % picture(0.977500,-0.245000)(2.450000,0.772500) x = 1.000000cm; y = -1.000000cm;

% set_line_color 0.000000, 0.000000, 0.000000
% set_line_color 1.000000, 1.000000, 1.000000
% set_line_color 0.000000, 0.000000, 0.000000
 label.rt(btex $A$ etex,(1.000000x,0.000000y));
endfig;
end;

################## VERSION 0.94 ###################

label.urt(btex {\usefont{OT1}{phv}{m}{n} $A$} etex scaled 1.67988,(1.000000x,0.000000y));
endfig;
end;


mpost chokes like this:

This is MetaPost, Version 0.641 (Web2c 7.3.7x)

Transcript written on test2.log.

But it writes the earlier version perfectly. Maybe I am being dumb here, I don't know much about metapost, I just want to blindly use mpost to convert the image as expected so I can include it in my latex document. I have found that I can still scale text using the etex scaled, but its the usefont bit that kills mpost.

Is the person who writes the mpost code on this list? Can somebody tell me how I am supposed to convert this 0.94 mp output to mps that can directly be included in a latex file for processing with pdflatex.
