When I tried to install the vagrant gem in ruby 2.0.0-p0 , I get the following error:
~ ruby -v ruby 2.0.0p0 (2013-02-24 revision 39474) [x86_64-linux] ~ gem -v 2.0.0.rc.2 ~ gem list json *** LOCAL GEMS *** json (1.7.7) ~ gem install vagrant Building native extensions.

I suppose its using json-1.5.5 from / home / user_name / .rvm / gems / ruby-2.0.0-p0 / gems / when building a gem and getting the above error.
I tried reinstalling the latest json-1.7.7 gem and still could not install it.
