Package Control didn't work in Mac OSX

This helped (taken from here)

1. Click the Preferences > Browse Packages… menu entry
2. Browse up a folder and then into the Installed Packages folder
3. Download Package Control.sublime-package and copy it into the Installed Packages directory
4. Restart Sublime Text

Install an RPM Package on Ubuntu Linux

Run this command to install alien and other necessary packages:

sudo apt-get install alien dpkg-dev debhelper build-essential

To convert a package from rpm to debian format, use this command syntax. The sudo may not be necessary, but we’ll include it just in case.

sudo alien packagename.rpm

To install the package, you’ll use the dpkg utility, which is the internal package management tool behind debian and Ubuntu.

sudo dpkg -i packagename.deb

The package should now be installed, providing it’s compatible with your system. Taken from here.
