Mysqlbug: Could not find a text editor. (tried emacs)

I want to check with what configurations mysql was configured. I found
that mysqlbug can retrieve that info, but i'm getting the following error:
mysqlbug
Finding system information for a MySQL bug report

Could not find a text editor. (tried emacs)
You can change editor by setting the environment variable VISUAL.
If your shell is a bourne shell (sh) do
VISUAL=your_editors_name; export VISUAL
If your shell is a C shell (csh) do
setenv VISUAL your_editors_name
