Hi,

I uploaded fixes for bugs #452340 and #671559 to the ocaml git
repository. I hope fixing bugs this way is fine.

Regarding 671559 and the use of debian-pkg-add-load-path-item I
added Pre-Depends: emacsen-common (>= 1.4.14) to ocaml-mode.
Alternatively one could drop the Pre-Depends and check 
(fboundp 'debian-pkg-add-load-path-item) in the install and
startup script.

Bye,

Hendrik
