If you name your macro (`kmacro-name-last-macro'), you can insert
it as a command in your init-file with `insert-kbd-macro'.

Or use a function.

(defun insert-perl-foo ()
  (interactive)
  (save-restriction
    (narrow-to-region
     (point) (progn
               (insert (expand-file-name default-directory))
               (point)))
    (goto-char (point-min))
    (when (re-search-forward ".*?/lib/" nil t)
      (delete-region (point-min) (point))) 
    (while (re-search-forward "/" nil 'move)
      (replace-match "::")))))
