Hi Ashish this often happens to me after reinstalling godi, if I forget to install one syntax extension used in my project. Instead of having a more meaningful message like 'missing package bidule', I've got the message you report. Maybe you could double check whether you installed all extensions used in sequme ? 2011/10/9 Ashish Agarwal > I get the error below after reinstalling OCaml with the latest version with > GODI.
