You will need to have nightly Haiku installed for this task.

Haiku uses HaikuDepot as it's package manager, but this requires packages and a way to build these packages. We use the tool HaikuPorter to to do this by telling it to read 'recipe' files that contains all the instructions needed to successfully build the package for Haiku. These recipes file can be found in a database called HaikuPorts, which it hosted on Bitbucket.

Head over to the wiki on the HaikuPorts website and go to the section called "Getting started" and follow the instructions on how to install HaikuPorter and the HaikuPorts database.

Now find a recipe that starts with the same letter that your username starts with and build a package with Haikuporter using that recipe. Instructions on how to use haikuporter can be found on this page under the "Building the recipe" section.
