问题
I have seen a number of posts on this before and have followed their instructions but nothing is working. I'll outline below what I have done, and the instructions I have follows - would be grateful for any advice!
I have followed the following installation instructions: http://pragmaticstudio.com/blog/2010/9/23/install-rails-ruby-mac
I have downloaded X-code for OSX Mountain Lion, and 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)
Copyright (C) 2007 Free Software Foundation, Inc.
This is free software; see the source for copying conditions. There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
I have then done as instructed and installed the latest version of git
$ git --version
git version 1.7.10.2 (Apple Git-33)
and similarly done the same with rvm via command line:
$ rvm --version
rvm 1.16.13 (stable) by Wayne E. Seguin <wayneeseguin@gmail.com>, Michal Papis <mpapis@gmail.com> [https://rvm.io/]
When I then try to install ruby using RVM, I get the following:
$ rvm install 1.9.3
No binary rubies available for: osx/10.8/x86_64/ruby-1.9.3-p286.
Continuing with compilation. Please read 'rvm mount' to get more information on binary rubies.

There has been an error while running configure. Halting the installation.
Using the alternate command line I get a similar output though the with some extra bits:
$ rvm install 1.9.3 --with-gcc=clang
-bash: -dumpversion: command not found
-bash: --version: command not found
-bash: --version: command not found

Looking into the configure.logs, I get the following:

checking whether the C compiler works... no
configure: error: in `/Users/mondemoo/.rvm/src/ruby-1.9.3-p286':

See `config.log' for more details
I'm now utterly confused as to what I have done wrong - is anyone able to assist?? It appears that there is an issue with the c-compiler (gcc?), am I interpreting it correctly? If so how do I fix that? Also how do I get to this "config.log" that is mentioned in the configure.log above?
Thanks!

This is a bug in RailsInstaller OSX 1.0.3 - https://github.com/railsinstaller/railsinstaller-nix/issues/10
you need to change /etc/rvmrc to contain this:
umask g+w
export -a rvm_configure_env
rvm_configure_env=('LDFLAGS=-L/opt/sm/pkg/active/lib' 'CFLAGS=-I/opt/sm/pkg/active/include' 'CPATH=/opt/sm/pkg/active/include')
I will prepare new version of the installer when binary ruby is available for 2.0.0.
UPDATE: for new version of RVM 1.19+ /etc/rvmrc should be changed to:
umask g+w
export rvm_autolibs_flag=smf
And run rvm get stabel #OR: head

Not sure I did it the 'correct' way, but I just removed RVM (rvm implode) and then reinstalled it (\curl -L https://get.rvm.io | bash -s stable --ruby) and it installed and is now running the latest version of ruby 1.9.3-p327 no problem.
