Trouble Installing Ruby 1.9.2 on OSX - Readline and Make errors

Solution 1:

Are you compiling Readline from source? It might be less painful to compile and install Readline via Homebrew, assuming that you have at least one working version of Ruby on your system.

Once you've done that, you can try the RVM install of Ruby 1.9.2 again, and it should skip the Readline compilation step.

Updated in response to comment:

So you are using a Homebrew installed Readline. In that case, find out where the new (less broken) Readline libs are installed, and try passing the location of that version of Readline to the RVM install process. Something like:

rvm install ruby-1.9.2-p320 -C --with-readline-dir=/usr/local/Cellar/readline/6.2.1

Clearly, your directory will be slightly different the one in my example.
