That may be the case for the Angstrom distro but it is not the case for the
Debian distro, which seems to be the future direction of BBB.

This link:

Seems to have the bulk of the requisite information including building a
GPS cape using the Adafruit GPS module. See:

This isn't a timing receiver but would probably be adequate for NTP. But
since I already have a T-bolt I figured I would use that as my timing
