Site build error locally

Ok, what am I doing wrong now?

I've just realised I haven't done brew update in a while. I'm running that and will update to opam 1.2.1 and maybe this issue will go away.

[amirmc]

That didn't help. I found my way to this, which indicates that this might be related to homebrew.

This seems to indicate that opam still thinks that your OCaml system compiler is 4.01 while you've updated your compiler version (with brew) to 4.02. You need to recompile your switch. Or to remove setup.data, call eval 'opam config env'and call make again.

I rebuilt the switch, reinstalled the packages, made sure I was on opam 1.2.1 and the site now builds just fine. Had a bit of a hiccup with ocaml-uri but it seems to have sorted itself out. Closing.
