This only happens when the file is not processed. There should be a file
with the suffix .mpt containing 

% figure 1 : texpictures[1] := btex \hbox spread 1em{\hss \strut Zapf
(1)\hss }

This file is generated in the first mp run, and then merged 

                doRunMP($MpName,0)  ;
                # test for labels
                my $belabels = 0 ;
                if (open(MP, "<$MpName.mpt"))
                  { while (<MP>)

See doRunMP for details. You may want to uncomment the line

# unlink "mptrace.tmp" ; rename ($MpFile, "mptrace.tmp") ;

and check the tmp file after a run for the zapf text. 

It works here, but when it works at your and other places as well, it would
be great, since then I can start embedding the graph package in context [i
already patched hobby's file to provide real tex texts instead of pseudo
text so that we can get real good labels and so].
