any recommendation for tutorials on functional programming

One point which people haven't mentioned is that it is not a good idea
point beginners, who wish to learn Erlang to texts that tell you how to
learn *other* FPLs.

If you are a beginner and want to learn X - find a beginners X text.

Once you know X it will be slightly easier to learn Y (if both  X and Y
are in the same family of FPLs)

Once you know X AND Y then it will be a tiny bit easier to learn Z etc.

FPLs fall into families, lazy, eager, strongly typed, dynamically typed

Knowing a language in one family will not help you with a language in
the other schools if you are a beginner.

Once you know Erlang well THEN you can try O'CAML (or vice versa)

To me this is like telling somebody who is interested in imperative
(especially Perl) to read a book on python - yes they have similar
concepts - but you
will only be able to see the similarities when you got pretty good at
both languages.

The golden rule of teaching things is "only confuse people with one
thing at a time" 

Learning Erlang is pretty easy - but not by reading an O'Caml book - the
concepts are
similar - but this is not blindingly obvious to a beginner.
