Rbenv cannot install rubinius

Question

I'm trying to install rubinius via rbenv and this error came out. I'm not sure what's wrong here.

Here is the (successful) result of installing jruby:

[app@onepiece-web02 log]$ rbenv install jruby-1.7.25

And here is the (failed) result of installing rubinius:

Without a full look at log file it's hard to know exactly what the problem is. I was able to install on OSX 10.9.4 with latest version of ruby-build installed with homebrew. I had to brew install llvm first however.

I suggest have a look at https://github.com/rbenv/ruby-build which rbenv install uses under the hood. In my experience with using rbenv install the issue is usually using the wrong c compiler, or missing libraries.

Some useful commands to check what your system defaults are:

which cc
which g++
cc --version
g++ --version

Check your $PATH settings echo $PATH
