Just confirm how to install ruby

[Ben Tung]

Dear sir,

I don't know much ruby, but I need ruby to run rmate.
I've installed the /usr/ports/lang/ruby20 , and I got
/usr/local/bin/ruby20

I don't why not /usr/local/bin/ruby, and it causes rmate doesn't work till
I
# ln -s /usr/local/bin/ruby20 /usr/local/bin/ruby

It works!

Just as I said I don't know ruby, and I just need to a ruby interpreter to
run rmate ( don't need ruby on rail or rvm )
so I am wondering if it is correct to put a link to /usr/local/bin/ruby20
Or, is there any correct way to set /usr/local/bin/ruby to
/usr/local/bin/ruby20?

Thank you for your attention,

Best Regards,

Ben
