Can't install Ruby on Mountain Lion 10.8.2

Question

I am running Mountain Lion v. 10.8.2 on my mac and Xcode 4.5.2

The version of ruby I am running is the default version 1.8.7. I want to upgrade to 1.9.3 but it's not working.

I installed the gcc compiler:

$ gcc --version 

i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)

$ git --version
git version 1.7.8

$ rvm --version
rvm 1.17.0 (stable) by Wayne E. Seguin <wayneeseguin@gmail.com>, Michal Papis <mpapis@gmail.com> [https://rvm.io/]

Then I tried to install Ruby 1.9.3 with the following command line:

$ rvm install 1.9.3

The output is this:

No binary rubies available for: downloads/ruby-1.9.3-p327.
Continuing with compilation. Please read 'rvm mount' to get more information on binary rubies.

Error running 'make', please read /Users/eduardo/.rvm/log/ruby-1.9.3-p327/make.log
There has been an error while running make. Halting the installation.

My make.log looks like this on the last couple lines:

collect2: ld returned 1 exit status
make[2]: *** [../../.ext/x86_64-darwin12.2.0/tcltklib.bundle] Error 1
make[1]: *** [ext/tk/all] Error 2
make: *** [build-ext] Error 2

Any help on this please? I am lost on how to fix this issue.
