It depends on the libev it was compiled with. It's unfortunate that you
can have both libev4 and libev-dev 3.x installed at the same time... on
the other hand, compiling lwt with libev-dev 1:3.9-1 generates the
correct dependency to libev3, and working packages, so it doesn't sound
right to version the dependency to libev-dev. I am not aware of another
way to fix this, though.

According to your original report:
> -- System Information:
> Debian Release: 6.0.1
>   APT prefers stable-updates
>   APT policy: (500, 'stable-updates'), (500, 'testing'), (500, 'stable')
> Architecture: i386 (i686)

you have both stable and testing in your sources.list, and you have
libev-dev from stable, and liblwt-ocaml-dev from testing. Are we
supposed to support such a mix as a development environment? Lwt is
surely not the only package in this situation...
