Simple answer: you have to put the files in the Makefile into the right
order. Since the generated module 'Lexer' depends on 'Parser' and module
'Fbot' on both you should write:

  SOURCES = parser.mly lexer.mll fbot.ml 

This should get rid of the problem. (In short: people have to
topologically sort the files according to their dependencies and sort
them totally wrt. their linking order).

Because the order of the modules also plays a role during linking (and
linking order matters, too, for side-effects!), there doesn't seem to
be any alternative to specifying the order manually in the general case.

Making files compile and link correctly by taking into account the
dependies only would make things much more complicated without really
solving the problem. It only gives the user the false sense that order
doesn't matter.
