Well, it should have been equally easy to use OMake in this case - while 
it is true that OMake is complex, the complexity is only there to help 
you out when you need it; you can safely ignore it until then.

If I understand what you are doing here correctly, it would have been 
sufficient to just use the following OMakefile:

---------
# Optional - use bytecode compilation even when ocamlopt is available
NATIVE_ENABLED = false
BYTE_ENABLED = true

USE_OCAMLFIND = true
OCAMLPACKS[] = ounit

.DEFAULT: $(OCamlProgram test, test easy easy_lexer easy_parser 
parser_util symtab parser_test)
-------

and then simply running "omake" would do what you want.
