I seem to have the main Ruby folder in /usr/lib/ruby. Is that the
correct place?
You’ve followed a standard installation procedure. Just leave
everything in the /usr directory and subdirectories
where it is, and make a directory
/home/me/ruby
(for instance by calling a shell and typing in
su
<Your superuser/computer administrator password>
cd /
mkdir /home/me/ruby
or by some graphical way Mac OSX provides)
You can then call your favourite editor, type some Ruby script,
save it in /home/me/ruby, and run it from there.
