[10:32:07] smathy:	shibly, but you can't reliably use the old gems with the new ruby.
[10:32:24] shibly:	smathy, Why not? What's wrong?
[10:33:15] smathy:	shibly, some gems have native (compiled) components, they won't work across different ruby versions.  This all is why version managers (and bundler) were invented.

[10:37:00] smathy:	shibly, chruby/rbenv and their install helpers: ruby-install or ruby-build
[10:37:23] shibly:	smathy, If i use rvm, then will i be able to use older gem with newer ruby?

[10:37:52] smathy:	shibly, no, you will never be able to do that for any gem that has a compiled component.

[10:40:00] shibly:	smathy, If i use chruby/rbenv then will i be able to use older gems with newer ruby?
