mruby 1.2.0 fails

Hi,

I'm trying to install mruby 1.2.0 (the latest version of mruby) on OS X 10.10.4.

λ →  ruby-install mruby 1.2.0>>> Installing mruby 1.2.0 into /Users/sunnyjuneja/.rubies/mruby-1.2.0 ...

When I try to install mruby 1.1.0, it successfully completes. If there's anything I can do to improve this issue, let me know. Thanks for all your hard work. I find ruby-install very useful.

Also, when I run clang -v, this is the output:

clang -v

I just had the same problem because I'd installed mruby 1.0 with rvm before trying to install mruby-head.
Switching my ruby version to MRI 2.2.1 fixed it for me.

I also got "... ./minirake:7: undefined method 'require' for main ..." on android [via Gnuroot].

Ohhh to clarify @xavriley 's comment, the problem is that ./minirake is trying to use mruby but it should use "real" ruby.

I had to change my project to use "real" ruby with rbenv local 2.3.0

So for me, it was fixed by

~/my-project/mruby $ make 
ruby ./minirake
trace:
    [0] ./minirake:7
./minirake:7: undefined method 'require' for main (NoMethodError)
~/my-project/mruby $ cd .. 
~/my-project $ rbenv local 2.3.0 
~/my-project $ cd mruby 
~/my-project/mruby $ make 
# compile output
