ERROR while compiling llvm2smt.dev

[flavluc]

I'm following the opam-termite installation guide and when I run opam install termite -v I get the error:

...
- ocamlfind: [WARNING] Package `threads': Linking problems may arise because of the missing -thread or -vmthread switch
- File "src/smtgraph.mli", line 12, characters 19-29:

- Command exited with code 2.

Any idea on how to solve it?
