When trying to install pg gem: Brew a bad interpreter error and a non-existent ruby ​​version

I really did something wrong when reinstalling rubies, rails, xcode, etc. (maybe even I uninstalled my Ruby installation system: /) Here is what I have now:

System: OSX 10.8.2 (64-bit)

which ruby gives me /usr/local/bin/ruby

I installed ruby 1.9.3p286 , Rails 3.2.8 and rvm 1.16.17 (stable)

I installed Ruby and Rails by following these tips: http://hivelogic.com/articles/compiling-ruby-rubygems-and-rails-on-snow-leopard

Next, I wanted to run gem install pg , but I have an error: No such file or directory - brew --prefix

I have only tried the brew command, but I have another error: /usr/local/bin/brew: bad interpreter: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin: no such file or directory

So, there is my question (I installed brew before) - why does it point to this 1.8 Ruby path if I don't have this version of Ruby installed? Can I somehow change this path to my current one with ruby ​​(which one from the ruby ​​team?)? How to fix this brew error? Please, help!

Ok, I get it - I edited the file: /usr/local/bin/brew and edited ther (first line) path: from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin to /usr/local/bin/ruby/ and now it works.

Does anyone know how to change the standard Ruby path to this? (to avoid problems with other programs in the future).

This did not work for me, but it set me on the right path ..... I had to do this:

sudo ln -s /usr/local/bin/ruby /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby

(and make the bin directory before hand)
