Breaking on build with Opam 1.2.2 and OCaml 4.02.3. #40

Open angrygoats opened 8 years ago

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.

Looks like a linking error due to lwt, can you link anything at all using let.unix?
