Comment (by mojca@…):

 I'm looking at options for git.

 The following commands result in stable checksums:
 {{{
 git archive {shasum_or_branch} > /path/to/name_version.tar
 gzip < /path/to/name_version.tar > /path/to/name_version.tar.gz
 }}}
 {{{
 git archive {shasum_or_branch} > /path/to/name_version.tar
 gzip -n /path/to/name_version.tar
 }}}
 {{{
 git archive {shasum_or_branch} | gzip -n > /path/to/name_version.tar.gz
 }}}
 {{{
 git archive {shasum_or_branch} | xz > /path/to/name_version.tar.xz
 }}}
 The first option results in a different checksum that the other two. I
 didn't try to understand the difference in the approaches, but in either
 case that would allow users to store the resulting compressed file, verify
 the checksums and store the file on MacPorts' server.

 (Optionally the resulting file could be touched to get the same timestamp
 as the contents, but that's not a strict requirement.)
