wrong file name

i get these weird loading problems on mac os x with homebrew-installed r:

No idea what's happening here. Looks like an ocaml packaging problem. How did you install ocaml-r?

[nilsbecker]

opam install ocaml-r

[pveber]

Looks right :). I've just built the library from a clean 4.07.1+flambda switch, and it works well. Unfortunately I have no mac at hand at the moment. Which version of opam do you use?

[nilsbecker]

i use opam 2.0.1. i'm also confused but i think i once saw a similar error message discussed somewhere online. not sure how to search for it though.

[nilsbecker]

this seems somewhat related https://caml.inria.fr/mantis/view.php?id=5832 . but in our case, the names are exactly the same?!

[nilsbecker]

ah no! the capitalization is indeed different!!

[pveber]

Indeed! What happens if you type open OCamlR?

[nilsbecker]

also, the cut-off error message for ocamlr_stats was

contains the compiled interface for
OCamlR_stats when OcamlR_stats was expected

which also has different capitalization

[nilsbecker]

OCamlR opens!

[nilsbecker]

and stats opens as well with the correct spelling. so i guess it's user error. although the error message could have been more helpful -- i would have expected something like no module OcamlR found etc\

[nilsbecker]

i also checked: i can successfully generate random numbers as in the readme

I agree, this is confusing. I found another issue on mantis describing a similar problem on Windows XP. Thanks for testing!
