Same just happened to me on Ubuntu 10.04 using RVM.
Anyways, my theory at the moment is they just released i18n 0.5.0 and
gem install rails installed 0.5.0 and mail gem requires i18n version
0.4.x.
Here's the entire painful process of getting it working.
abarrin...@andys-dev-box:~$ gem install rails
