# for Linux on a virtual host is somewhat messy. So here is what 
# I did to make it work.

# Install the packages required
yum update
yum install gcc kernel-devel make bzip2

reboot

Out of the box, Homebrew does a default installation on Sphinx:

$ brew install sphinx

However, if you're using MySQL, the thinking-sphinx gem won't work because it needs to use MySQL libraries.

If you managed to screw up the first time, uninstall sphinx first:

$ brew remove sphinx
