Ugh, this is quite painful. Spend 2+ hours on this.

If i use this:
(add-to-list 'load-path (file-name-directory load-file-name))

it works if the file is loaded by elisp. But doesn't work if the file
is run with eval-buffer.

The following works with eval-buffer but not when the file is loaded.
(add-to-list 'load-path default-directory )

What can one do?

I want a method to add the current file's dir to load-path, and it
should work either the file is loaded by elisp or run by hand with
eval-buffer.

Thanks.
