The repository of record is CVS, but you can - like many of us do - use either the hg export (https://anonhg.netbsd.org/pkgsrc) or GitHub (https://github.com/netbsd/pkgsrc) instead.

At some point we will transition the repository of record to something else, but it's being done carefully. We want to do it right, and there aren't many volunteers willing help with the work.
