I'm using netstring (from ocamlnet 4.1.6) which has a dependency towards netsys and the following error message appeared when I tried to compile everything:

Error: No implementations provided for the following modules:
         Thread referenced from /home/kit_ty_kate/.opam/4.06.1/lib/netsys/netsys_oothr_mt.cmxa(Netsys_oothr_mt)
         Mutex referenced from /home/kit_ty_kate/.opam/4.06.1/lib/netsys/netsys_oothr_mt.cmxa(Netsys_oothr_mt)
         Condition referenced from /home/kit_ty_kate/.opam/4.06.1/lib/netsys/netsys_oothr_mt.cmxa(Netsys_oothr_mt)

When I manually added threads to the netsys requirements, compilation succeeded.
