问题
I had a fresh install of Mountain Lion and installed the Xcode Command Line Tools, . I was able to get homebrew running and installed RVM. Unfortunately, I can't get RVM to install ree-1.8.7-head. It fails when compiling. I thought it was related to X11, so I installed XQuartz. Still no joy. Then I went ahead and installed the full Xcode from the app store. Still no joy. Anyone gotten this going on a fresh Mountain Lion install?
From the bottom of the .rvm/log/ree-1.8.7-head/make.log:
Find Tcl/Tk libraries. Make tcltklib.so which is required by Ruby/Tk.

回答1:
try
rvm reinstall 1.8.7 --without-tcl --without-tk
but still your problem might to be related to gcc-4.2 -> it's required for MRI ruby, there are some successes with llvm/clang, but still it fails with Fibers
回答2:
If you don't need tcl or tk and are using 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
