In that case you must configure gs to know about /cmr10 (thru fontmap 
file, see also the corresponding file fontmap.cm in your /gs/lib 
directory; the path to cmr10.pfb must of course correspond to your real 
path). But if you will use the same code with
prologues:=3;
you will obtain eps file with cmr10.pfb included which will than work 
correctly in any further processing.

Happy mp-ing,
