If that is the only step you're missing then you have probably missed  
the res.rc rule from MakeDll when creating your Makefile:

$(DLLNAME)_res.rc:
         @PERL5LIB=$(RHOME)/share/perl $(PERL) $(RHOME)/src/gnuwin32/ 
makeDllRes.pl $(DLLNAME) > $@

Cheers,
Simon

PS: Given that you can override any rule, it is usually easier to just  
write your modifications in Makevars[.win] when fiddling with the  
compilation than to replicate the whole process.
