Trying to install rails 3 on a new macbook pro.
$ rails -v
Could not find bcrypt-ruby-2.1.2 in any of the sources
$ bundle install
Installing bcrypt-ruby (2.1.2) with native extensions /Library/Ruby/
Site/1.8/rubygems/installer.rb:483:in `build_extensions’: ERROR:
Failed to build gem native extension.
mkmf.rb can’t find header files for ruby at /System/Library/Frameworks/
Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/bcrypt-
ruby-2.1.2 for inspection.
Has anyone else had this problem with bcrypt?
