I was getting a similar error (on macos 10.6.8). In the output of 'make' I 
noticed the line
   /bin/sh: firstflex: command not found

I modified the Makefile rule for scan.c and added $(srcdir) in front of 
$(FIRSTFLEX)
           $(srcdir)/$(FIRSTFLEX) ....

That seems to fix the problem. Delete scan.c before you try make again.
