Ruby 1.9.3 segfault in OSX Lion due to OpenSSL

I just set-up my new MacBook Pro, running OSX Lion (10.7.3), for Rails development. Installed rvm, installed Ruby 1.9.3 using rvm and did a gem install rails -v 3.2.3. Everything went fine, until I tried to create a new rails app.

rails new <app_name> would create the app structure, but would then fail with a segfault in http.rb. Here’s what the stacktrace looked like:

run  bundle install
/Users/CodeMangler/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/1.9.1/net/http.rb:799: [BUG] Segmentation fault
ruby 1.9.3p125 (2012-02-16 revision 34643) [x86_64-darwin11.3.0]

So, the failure was while doing a bundle install at the end of creating a new rails application, which’s new in rails (to me anyway. It’s been a while since I last looked into rails).
Googling for ruby segfault in http.rb pointed towards issues with OpenSSL. Then I found this post that describes how to fix the issue:

It tuns out, you’ve to install the openssl package for rvm, and then, while installing ruby, point it to use this version of OpenSSL.

To quote steps from the post:

$ rvm pkg install openssl
$ rvm remove 1.9.3 # uninstall the existing version, if you've installed one
$ rvm install 1.9.3 --with-openssl-dir=$rvm_path/usr --with-gcc=clang

Do that, and you should be all set. I tried creating a new rails app after that, and it went through just fine. Also, from googling, it appears that if it’s a segfault in http.rb, it’s most likely due to OpenSSL.
