Why are gems installed in a directory with a different Ruby version than I’m running?

Question

When I install a gem, it gets installed in a directory named 1.9.1, despite that not being the version of Ruby I have installed:

$ ruby -v
ruby 1.9.3p327 (20

I believe it's because they share the same standard library.

There were some significant upgrades in the 1.9.2 core, but I don't think anything in the standard library was changed, so they share the same path. It's nothing to worry about, though — as you said, everything is working fine.
