Do you use RVM? Do you use MacPorts? Have you installed openssh via MacPorts? And have you torn your hair out when trying to compile Ruby 1.9.x and gotten errors like this:
% bundle install

You are most likely to have been in my position for the past day or so where unfruitful searches for “rvm” and “http.rb:799: [BUG] Segmentation fault” turned up not much conclusive. There are a number of posts on StackOverflow which seem to be talking about this and even a very detailed post, but I found the solutions to be incomplete. Then I chanced across the Using MacPorts with RVM page. It turns out that using MacPorts will install openssl but in a different place than what RVM is expecting, hence because your Gemfile most likely has:
gem 'rails', '3.2.1'
Rails/bundler is going to try to use openssl, but of course http.rb is going to fail with a:

Not happy. Worse yet, many of the solutions just say to use “with-openssl-dir”, but that didn’t completely solve it for me.
Fortunately the official RVM page has an incantation if you want the MacPorts’ installation of openssl: add this to your master $HOME/.rvmrc:
export CFLAGS="-O2 -arch x86_64"
Follow that up with a basic install of 1.8.7:
rvm install 1.8.7 --with-openssl-dir=/opt/local
And finish that with the actual Ruby version of your choice:
rvm install ruby-1.9.3-p194 --with-opt-dir=/opt/local
(You can also do an rvm reinstall.)
The happy result?
rvm reinstall ruby-1.9.3-p194 --with-opt-dir=/opt/local

Note the fact I also had done a sudo port install libyaml. Also note that should that fail, you may have to do the manual installation of libyaml per instructions on http://pyyaml.org/wiki/LibYAML:
% make install (or "sudo make install")
