 Because LLVM is built as part of building Swift and does not include some of the patches to handle the OpenBSD library naming convention, you will need to create some symlinks:

 ## Downloading the source
 
 Download the sources with the [Getting Started](/docs/HowToGuides/GettingStarted.md) guide (see "Cloning the project"). Use the config file below when running `update-checkout` by specifying the file name with the `--config` flag. This config file just prepares cmark, LLVM, and Swift (as this is the minimal set of dependencies which has been tested for OpenBSD).
