Is it possible to reinstall/fix Mac OS X’s system ruby without doing a complete OS reinstall?

As the title says, I deleted Ruby.Framework how can I get it back? I don't have a OS X CD, (2012 MBP Retina Factory Installed OS X).

Any tips would be great thanks.

This question was marked as an exact duplicate of an existing question.

Do you want to rescue deleted files or reinstall it. Explaining how you deleted it would also help you get better answers. – Martín Canaval Feb 2 '13 at 5:08

Ruby.framework comes with OS X install, I fixed it by using Pacifist.. Next.... – Gacnt Feb 2 '13 at 6:21
Awesome! So here's what we gotta do... Write what you did to solve your issues (details) in another answer box and mark it as solved. Then, I'll delete my answer above leaving this a nice, clean problem/solution ; ) – Josh Campbell Feb 2 '13 at 6:25
Turns out this question was already asked and answered, so I linked it as a dupe (which also means @Gacnt can't post an answer here). But the other post mentions Pacifist as well, so I guess we're fine. – slhck Feb 2 '13 at 11:07

You could also have started up from the recovery partition and done an upgrade install of OS X. If 10.8 was preinstalled, it downloads the installer from the internet for free. It shouldn't affect most user files, and it can also fix other issues, so it's not necessarily overkill.
