[Matlab-emacs-discuss] mlint not working, void variable

[Nicholas H. <nic...@gm...>]

Hi and thanks for the package!

I'm trying to get linting to work, but nothing will show. I would love help
debugging.
My steps:
1. Open .m file and turn on matlab-mode
2. Turn on mlint-minor-mode
3. Run mlint-buffer

This is run from emacs -Q with packages loaded first and variables to
executables set. Apparently something right is happening since I see some
lines in the *M-Lint* buffer, but I get the following error and stack trace:

Any ideas?
