I won't go into the details of why I did this because I already feel stupid enough but I deleted ruby from the use/bin folder and now Brew does not want to work.
How can I fix this?
(I am on Lion)

Can't you restore this file from a Time Machine backup?– raimueSep 17, 2011 at 9:18

no time machine here (yes, I know...). Tried to reinstall Xcode but it did not add it back– AlainSep 17, 2011 at 20:04

This isn't answer but you can replace the remove command with an alias to just move the file to a folder to store your files before you decide to permanently delete the files. It's like to have a trash desktop icon but on the command line. You can either replace rm or create a new command for example del. If you replace rm command and you want to delete a file just move the file to /dev/null.– MicromegaDec 1, 2011 at 1:24

Ruby isn't a critical system file (as far as I know), so I'd imagine you should be able to reinstall it. Just follow the same procedure you did to install Ruby in the first place. See e.g. official instructions.
On a standard system, /usr/bin/ruby is a symlink to ../../System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ruby
If you still have that file, you can just link it back:
sudo ln -s '../../System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ruby' /usr/bin/ruby
