You `(require 'sclang)` cause error on `(require 'sclang-vars)` failed. Because there is no file `sclang-vars.el`. Only file `sclang-vars.el.in` for built-time defaults. When user load sclang from source code of `scel`. This will cause error.

Really don't understand why you have to `(require 'sclang)` instead of `(require 'sclang-interp)`? Can you tell me why?
