nodejs on Fedora 19

[Roger]

<snip>
I yum removed nodejs which removed all v8 s as well then yum installed 
nodejs which installed Package v8.x86_64 1:3.14.5.10-1.fc19 Rails 
requires nodejs which requires v8.

Huh? A `yum install rubygem-rails` does not drag in nodejs. I'm curious 
as to what does; it probably should be using rubygem-execjs instead.

The v8-3.17.6.14-2 package comes from spot's Chromium repository, which 
unfortunately conflicts with the v8 in the main Fedora repositories. 
Chromium uses much newer versions of v8 that have completely broken the 
API relied on by nodejs and binary extension modules [1], so you can't 
use chromium and nodejs at the same time. :-( The fact that yum tries to 
drag in v8.i686 is a minor packaging bug with nodejs. The easiest way to 
work around it is to remove the chromium repo,

rubygem-execjs seems to be just a tool that looks for and executes 
nodejs and baulks if it doesn't find it.
I don't use chromium, it would not install into my fedora19 so I went 
grudgingly for google chrome and Opera instead.

Removed the chromium repo.
I hope it works
