I have OPAM 1.2.0 installed. When I try to install lwt, I get:

$ opam install lwt
Your request can't be satisfied:
  - lwt.2.4.5 is in conflict with ssl.0.5.0

No solution found, exiting

opam info lwt shows version 2.5.0 is available (along with many other versions) but when I try to install it, I get:

$ opam install lwt.2.5.0
Your request can't be satisfied:
  - No package matches lwt.

No solution found, exiting

I get the same error if I try to install version 2.4.8. This seems like the OPAM config for lwt may have a bug. Can anyone else install the latest lwt using OPAM 1.2.x?
