How to upgrade from Ruby 1.9.2p0 to ruby 1.9.2p180 without rvm?

I have searching around for upgrading ruby 1.9.2p0 to ruby 1.9.2p180 as I got some compatibility issues in my application. I searched on web and studied but am unable to do it. I know that this has already been discussed a lot, but still I'm unable to figure it out. Also I don't want to use rvm. So looking for fast开发者_高级运维 responses with simple ways to upgrade ruby 1.9.2p180.

Just go to the ruby site, and download it. Extract it, cd to the extracted directory, then do as usual:

./configure
make
sudo make install

Either look for another universe that has a more recent package or install from source.
