Breaking on build with Opam 1.2.2 and OCaml 4.02.3. #40
Description
I am running OCaml 4.02.3 with Opam 1.2.2 on NixOS. I have successfully built lwt 2.5.2 via opam install lwt.
Now when I try to build lamda-term I end up with this error:
### stdout ###

Do you know what could be causing this? Its the only thing keeping me from building utop successfully with opam.
