Homebrew's Ruby 1.9 ships with rubygems. Doing gem install ... installs files and binaries into some long-winded path. For example, bundler is installed at:
/usr/local/Cellar/ruby/1.9.3-p0/lib/ruby/gems/1.9.1/gems/bundler-1.0.21/bin/bundle
I'd like to have gem automatically symlink these binaries into a common location such as /usr/local/bin so that I don't have to manually link each of these binaries. Is this possible?

This little one-liner works perfect and is faster than querying brew-info:
export PATH=$(brew --prefix ruby)/bin:$PATH
More info in my answer there.
# Install 1 or more gems
gem install rails
gem install aws-sdk
# Then run these 2 commands to create bin links
brew unlink ruby
brew link ruby
# Finally open a new terminal session (no idea why but it worked for me)
I ended up adding the following lines to .bashrc
RUBY_BINDIR=`brew info ruby|grep /bin|tr -d ' '`
export PATH=$RUBY_BINDIR:$PATH
The afore-mentioned brewbygems is not what you want, it's meant for the osx-builtin ruby and homebrew to play nice together, not if you installed ruby itself via homebrew.
This worked for me: brewbygems
I followed the instructions on that site, and installed the 'brewbygems' gem before (re)installing my ruby gems. As far as I can tell, brewbygems extends the gem system to make it aware of Homebrew. It then takes care of symlinking in the binaries when gems are installed.
If you don’t want to touch your dot file, You can try:
brew unlink ruby && brew link ruby
New gems binaries symlinks will be created:
Unlinking /usr/local/Cellar/ruby/2.0.0-p0... 20 links removed
Linking /usr/local/Cellar/ruby/2.0.0-p0... 25 symlinks created
