I have used
sudo gem install to install a few gems. My question is how do I know where the executable was installed, so I can add it to the path in
Ruby "Gems" are not generally applications, most often they are libraries. From the Ruby Gems website
1.1 Really Quick Start Question: I’ve installed RubyGems and I want to install Rails (for example). How do I do that?
gem install rails
1.2 What is a Gem?
A gem is a packaged Ruby application or library. It has a name (e.g. rake) and a version (e.g. 0.4.16).
Also, see this information on how to inspect a gem:
2.5 Looking at an installed gem When you run
gem specification progressbar # shortcut: gem spec progressbar
you will see all the details of the ’’progressbar’’ gem.
You should consult the documentation which came with the gem, or, post more details so we can assist you more.
gem env command to display where Gems stores everything.

However, to avoid having to use
sudo to install gems into the System version of Ruby, I use RVM, which sandboxes all my gems plus any additional versions of Ruby I want to install. I've been using it for a while and love it.
Also if you type: gem list
then you will get a list of all the gems that you have installed. At least that way you can check to see if it installed properly and which ones you currently have installed.
The path to my gems on my Windows PC is:
Probably the same location/file hierarchy on the Mac as well. (except for that whole
C:/ part ;-)
I took the following quote from the page talking about installing Sproutcore. It might help you in figuring out this path issue. Let me know! (I am a n00b when it comes to this stuff. I just starting learning it yesterday! But I found lots of helpful information!)
if you faced a problem during the last part then this probably because the PATH of the gem isn't the default one. You can call the command as
/var/lib/gems/1.8/bin/sc-init HelloWorld cd hello_world sc-server
Or you may reconfigure the path by running the following command
PATH=/var/lib/gems/1.8/bin export PATH
Then rerun sc-init command.
Now visit http://localhost:4020/hello_world to see your handiwork.
