Error when installing Ruby 1.9.3 on Mac OS X Lion

I'm trying to install Ruby 1.9.3 and Rails on MAC OS X Lion. (My Xcode is version 4.3) (I've installed Rails 3.2.2)

No matter if I use:

rvm install 1.9.3 --with-gcc=clang

or:

rvm install 1.9.3

My terminal shows:

Error running 'make ', please read /Users/AlexHo/.rvm/log/ruby-1.9.3-p125/make.log
There has been an error while running make. Halting the installation.

Has anyone encountered the same situation?

I had this problem myself, and after a great deal of struggle and searching (not one site had the complete solution), here's what I finally came up with:

curl -O ftp://ftp.gnu.org/gnu/readline/readline-6.2.tar.gz
tar xzvf readline-6.2.tar.gz
cd readline-6.2
./configure --prefix=/usr/local
cd shlib
sed -e 's/-dynamic/-dynamiclib/' Makefile > Makefile.good
mv Makefile.good Makefile
cd ..
make
sudo make install
cd ..
rvm install 1.9.3 -C --with-readline-dir=/usr/local/

Try looking at this, it seems that your problem is with readline, and rvm has a whole section about working with readline errors.
