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.
