 The basic FreeSWITCH™ prerequisite packages are installed by running the following command (copy/paste the entire line) in Terminal from any directory:
 
 ```xml
-brew install autoconf automake curl ffmpeg@5 jpeg ldns libpq libsndfile libtiff libtool lua openssl opus pcre pkg-config sofia-sip speex speex speexdsp sqlite yasm signalwire/homebrew-signalwire/libks signalwire/homebrew-signalwire/signalwire-c signalwire/homebrew-signalwire/spandsp

-brew link ffmpeg@5
+brew link ffmpeg@5 libpq@16
 ```
 
 Ignore any _keg-only_ messages, they mean an alias (link) for the package was not placed into /usr/local/bin because brew found that macOS has another version installed. This is not a problem because the FreeSWITCH™ installation process searches Homebrew directories to find prerequisite packages.
