Comment (by ryandesign@…):

 I'm not sure how this relates to this ticket. The solution I'm envisioning
 for this issue (in Subversion parlance, though I'm sure git and hg have
 equivalent concepts) is maintaining a persistent working copy which would
 be updated and switched as needed, or in extreme cases deleted and
 recreated, not creating any tarball, keeping any checksums, or uploading
 any file to a MacPorts server.
