Does not compile on OS X

[andrejbauer]

Here is my Opam setup:

$ env | grep opam
CAML_LD_LIBRARY_PATH=/usr/local/opam/4.01.0/lib/stublibs
MANPATH=/usr/local/opam/4.01.0/man:
PERL5LIB=/usr/local/opam/4.01.0/lib/perl5
OPAMROOT=/usr/local/opam
OCAML_TOPLEVEL_PATH=/usr/local/opam/4.01.0/lib/toplevel
PATH=/usr/local/opam/4.01.0/bin:/Library/Frameworks/Python.framework/Versions/3.4/bin:/Users/andrej/bin:/Users/andrej/.cabal/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/usr/local/MacGPG2/bin:/usr/texbin

I am on master branch of Eff, commit 5ad3b54.
When I run ./configure it gets wrong the directory in which Ocaml binaries are found:

$ ./configure 
Configuration: 
ocamlfind: ........................................... /usr/local/opam/system/bin/ocamlfind
ocamlc: .............................................. /usr/local/bin/ocamlc.opt
ocamlopt: ............................................ /usr/local/bin/ocamlopt.opt
ocamlbuild: .......................................... /usr/local/bin/ocamlbuild

And so compilation fails:

$ make
ocaml setup.ml -build 
Finished, 1 target (0 cached) in 00:00:00.
/bin/sh: /usr/local/opam/system/bin/ocamlfind: No such file or directory
Failure: Error while running: /usr/local/opam/system/bin/ocamlfind list.
Compilation unsuccessful after building 0 targets (0 cached) in 00:00:00.
E: Failure("Command ''/usr/local/bin/ocamlbuild' src/eff.native -tag debug' terminated with error code 2")
make: *** [build] Error 1

Did you try to remove setup.data and rerun ./configure? I think I had to run it twice for it to reflect the current state of OPAM.

I cannot reproduce the problem anymore. Something in opam got updated, apparently.
