Probably package-initialize is called in your init file after that
add-to-list. If you do not a call to package-initialize in your
init file, it gets added to it automatically by package.el.
If you install packages with elpa you do not need the add-to-list,
package-initialize takes care of adjusting the load-path and using
require in the latest installed version of each package.
