“Ago” is frequently used with the present perfect tense and the word “since”. Since + time + ago states a specific point in the past, and then the present perfect is used to show that the situation still exists and could continue into the future.
“I haven’t played baseball since two years ago, (when I injured my knee).”
“He has been practicing the trumpet since an hour ago.”
“That store has been out of business since three weeks ago.”

What about this, Jamie?
“Since a long time ago” (“a long time” is not really a specific point, is it? :P)
