I try to compile an Ocaml project with an Ocaml version provided by Opam. My ocamlbuild, ocamlfind, and oasis seem OK :
/Users/fred/.opam/4.02.1/bin/ocamlbuild
dhcp-182-73:compil fred$ which ocamlfind
/Users/fred/.opam/4.02.1/bin/ocamlfind
dhcp-182-73:compil fred$ which oasis
/Users/fred/.opam/4.02.1/bin/oasis
But when I try to compile, it seems that a wrong version of ocamlbuild is called, and even the version of ocamlfind is right, I think that it explains why ocamlfind can't find the sexplib library.
$ make
ocaml setup.ml -build

I've tried to tell oasis which version of ocambuild to use without success, does someone knows how it could be done ? Thanks
Try deleting setup.data and running make again. Oasis caches the paths the first time you try to build, and doesn't update them automatically afterwards. Perhaps you tried to build it, then used opam switch, then tried to build it again?
