Comment (by aggraef@…):

 Replying to [comment:5 ryandesign@…]:
 > MacPorts does provide an `ln` procedure which works similarly to the
 shell command of the same name. In this case, invoking it in a `post-
 extract` block would be reasonable.

 Great. I imagined that there must be some official way to do this but
 couldn't find it in the docs.

 > I'm not sure in which version of OS X gzip gained that ability, but we
 should handle this as if gzip only understood gz files, and manually
 extract the reduce tarball in a `post-extract` block. That would also give
 us the opportunity to extract it directly into the pure directory,
 avoiding the need to make a symlink.

 Seems like a good idea! But I can also repackage the tarball as a .tar.gz
 and upload that if it makes things easier. Just let me know.
