f038291293 Don't silently fail if ocamlfind cannot be found when building the Ocaml 
bindings is enabled. That is really unhelpful behaviour. Instead emit a
warning. I would prefer an error message but apparently being able to
build but not install the OCaml bindings is desirable.

Whilst I'm here also print information about ocamlfind where it should
have been mentioned.

131f9e2247 change queries to take function names instead of arbitrary predicates. This allows to bypass issues with having arbitrary query expressions compiled in arbitrary ways to auxiliary predicates where names of bound variables are reshuffled.

bindings are enabled and the set python package directory does
not live under the install prefix. This is the other part required

e9ea687bb9 Disable the Python bindings by default which partially fixes issue #404. 
To enable the Python bindings use the newly added ``--python`` option.
