Install ree-1.8.7 using RVM on Mountain Lion

Question

I had a new installation of Mountain Lion and the Xcode command line command was installed. I managed to start homebrew and install RVM . Unfortunately, I cannot get RVM to install ree-1.8.7-head . When compiling, it fails. I thought this was due to X11, so I installed XQuartz . There is no joy yet. Then I went and installed the full Xcode from the app store . There is no joy yet. Has anyone got it on the new Mountain Lion?

Below .rvm / log / ree-1.8.7-head / make.log :

Answer 1

to try

 rvm reinstall 1.8.7 --without-tcl --without-tk 

but still your problem may be related to gcc-4.2 → it is necessary for MRI rubies, there are some successes in llvm / clang, but still it fails with Fibers

Answer 2

If you don't need tcl or tk and you use rbenv, this should work:

 brew install https://raw.github.com/Homebrew/homebrew-dupes/master/apple-gcc42.rb CC=/usr/local/bin/gcc-4.2 CONFIGURE_OPTS="--without-tcl --without-tk" rbenv install 1.8.7-p358
