Rails with Mavericks

r_with_mav.txt

I tried doing a bundle install with rails and had immediate problems like 

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

    /Users/dineshvasudevan/.rvm/rubies/ruby-1.9.3-p392/bin/ruby extconf.rb
checking for random()... *** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

You have to install development tools first.

I use rvm. And Mac Ports ... I tried to reinstall the ruby with 

sudo rvm reinstall ruby

The problem was that Macports did not work with Mavericks

So I had to reinstall .. http://trac.macports.org/wiki/Migration

After that we reinstall ruby (rvm list and then all the versions)

DOESNT WORK

Stared installing rbenv !

implode rvm

Installed rbenv and all the ruby versions
Problem with libv8 --> Used RUBYGEMS as RUBYOPTS
Added CC and RUBYOPTS to the `bash_login/bashrc`

therubyracer doesnt work. Does not find lib/ruby/gems/1.8/gems/libv8-3.3.10.4/lib/libv8/build/v8/libv8.a
Problem ? the gcc is not set properly. 

https://github.com/cowboyd/libv8/issues/46

Run `scons arch=x64` on the v8 directory .. Doesnt work because of the gcc/g++ problem
Run it like `CC=gcc-4.4 CXX=g++-4.4 scons arch=x64` .. IT WILL WORK !
