Source Package for caf?

About a year ago, I was trying to get the Bro test suite running in Travis CI. To make this easier, I was trying to get caf added as a whitelisted package to Travis CI. Unfortunately, this failed because there was no source package available for caf:

Does anyone know if a source package for caf now exists? Thanks,
