 - `apt-get install libpolarssl-dev` if you want to use PolarSSL, or use OpenSSL/libcrypto otherwise.
 - `apt-get install libsoxr-dev` if you want support for libsoxr-based resampling. This library is in many recent distributions, including Jessie and Raspbian Jessie; if not, instructions for how to build it from source for Rasbpian/Debian Wheezy are available at [LIBSOXR.md](https://github.com/mikebrady/shairport-sync/blob/development/LIBSOXR.md).

 A final consideration is the location of the configuration file `shairport-sync.conf`. This will be placed in the directory specified by the `sysconfdir` configuration variable, which defaults to `/usr/local/etc`. This is normal in BSD Unixes, but is unusual in Linux. Hence, for Linux installations, you need to set the `sysconfdir` variable to `/etc` using the configuration setting `--sysconfdir=/etc`.

 To complete the installation, you need to define a `shairport-sync` group and user. This is a security measure – the user and group are relatively unprivileged, and the user does not have login priviliges. The user must be a member of the `audio` group to be able to access the audio hardware. The following commands define the group and user correctly if they do not already exist (note the use of `sudo` – omit this if you already have superuser privileges:
