RVM Does Not Install Ruby 1.9.2 on Snow Leopard: 'Error running 'make '

Question

When I try to install Ruby 1.9.2 on Snow Leopard using:

rvm install 1.9.2

I get the following:

ERROR: Error running 'make ', please read /Users/mary/.rvm/log/ruby-1.9.2-p180/make.log
ERROR: There has been an error while running make. Halting the installation.

So, I check out make.log. The end of it reads:

readline.c: In function ‘username_completion_proc_call’:
readline.c:1386: error: ‘username_completion_function’ undeclared (first use in this 
function)

readline.c:1386: error: (Each undeclared identifier is reported only once
readline.c:1386: error: for each function it appears in.)
make[1]: *** [readline.o] Error 1
make: *** [mkmain.sh] Error 1

I have consulted other answers to this question, and done everything suggested there:

• XCode is installed.

• The end of my .bash_profile has the following line added to it:

  [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
  

I have tried updating readline, but no matter what, I continue to get the error message about running 'make.'

The output of rvm info is the following:

Any suggestions would be appreciated.

Compile and install your own readline:

curl -O ftp://ftp.gnu.org/gnu/readline/readline-6.1.tar.gz
tar xzvf readline-6.1.tar.gz
cd readline-6.1
./configure --prefix=/usr/local
make
sudo make install
cd ..

Remove the ruby: rvm remove 1.9.2

Install it again: rvm install 1.9.2

(You might need to add source it if local path is not in your directory: rvm install 1.9.1 -C --with-readline-dir=/usr/local/

That should do it.

------------- EDIT --------------

As noted in the comment below, if you use homebrew, then you should brew install readline. And if you're using a Mac, you should be using homebrew.

------------ HOW TO COMPILE READLINE ON 10.7 ---------

"readline-6.2 has not been updated for Mac OS X 10.7 (darwin11), so open the support/shobj-conf and change darwin10 to darwin11 in the two places where it appears."
