The blog with no name

Things to know before following these directions:

• I don’t use MacPorts or Fink. There is nothing wrong with using either of them, I just prefer not to.
• I’m doing this on an Intel Mac running Mac OS X 10.5.7, no guarantees for any other
• architecture or OS X version
• i use ~/source for most of my development work.
• I wrote this for some of my less system minded co-workers

Install GNU Readline. Skip this step if you already have readline installed. You may also use Fink or MacPorts to install.

• cd ~/source
• curl -O http://ftp.gnu.org/gnu/readline/readline-6.0.tar.gz

• tar xvzf readline-6.0.tar.gz
• cd readline-6.0
• ./configure
• make
• sudo make install

• Install Ruby 1.9.1:

• cd ~/source
• svn co -r23858 http://svn.ruby-lang.org/repos/ruby/branches/ruby_1_9_1
• cd ruby_1_9_1
• ./configure –prefix=/opt/ruby -enable-shared –with-readline-dir=/usr/local (if you already have 
readline installed, change the last part accordingly)
• make
• sudo make install

• cd ~
• vim .bash_profile
• add this line: alias ruby-19=’export PATH=/opt/ruby/bin:$PATH’
• save the file and exit vim

Install notes for some common gems:

• enter ruby -v to make sure you’re using the correct version of ruby. It should report version
• 1.9.1p203, if not, enter the ruby-19 command created above.
• MySQL - install hectoregm-mysql-ruby. The mysql gem doesn’t work on Ruby 1.9
• rspec and rspec-rails. You need to also install test-unit v1.2.3 for rspec-rails to work properly.
• Make sure that v1.2.3 is the only one installed. If you also have a newer version installed, things 
won’t work.
• mongrel - needs to be patched using these directions http://isitruby19.com/mongrel . If you 
followed my directions, change the path in step 1 to /opt/ruby19/lib/ruby/gems/1.9.1/gems/mongrel-1.1.5/ext/http11
• mongrel_cluster
• check http://isitruby19.com for other gems
