The iPhoto Library Upgrader prepares libraries from iPhoto '08 (v7.x) or earlier so that you can use them with the current version of iPhoto or Photos for OS X. If your library was created by iPhoto '09 (v8.x) or later, you don't need to use this tool.

OK, then that should work. Make a folder called 'iPhoto Library' (in fact, call it whatever you want - it will be your new iPhoto Library folder) and put it wherever you want to. Then ctrl+click it and choose 'Make Alias.' Move the alias to /Pictures and rename it 'iPhoto Library.' Apple has brought Photo Library with its latest OS X update 10.10.3.
