What is Octopress anyway

Here is a short description from octopress.org:

Octopress is a framework designed by Brandon Mathis for Jekyll, the blog aware static site generator powering Github Pages. To start blogging with Jekyll, you have to write your own HTML templates, CSS, Javascripts and set up your configuration. But with Octopress All of that is already taken care of. Simply clone or fork Octopress, install dependencies and the theme, and you’re set.

How to configure octopress

The document presented by octopress itself is really great, you car refer How to deploying to github for more details (as what I did).

I found a weird issue when try to generate

FIX for Lion’s posix_spawn_ext.bundle: [BUG] Segmentation fault

First delete the ruby

rvm remove ruby-1.9.3 --gems --archive

then

echo $CC

should return none.

finally, reinstall all stuff

CC=/usr/bin/gcc-4.2 rvm install ruby-1.9.2
gem install bundler
bundle install

should fix the error.
