Comment (by ryandesign@…):

 Ok. Then to the remaining issues:

 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.

 The other problem is that you've specified both a tar.gz distfile and a
 tar.bz2 distfile. MacPorts is currently not designed to be able to extract
 multiple distfiles unless they are all of the same type. So the fact that
 this is getting past the extract phase at all is surprising, and seems to
 indicate the /usr/bin/gzip at some point gained the ability to understand
 bz2 files. 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.

 I'll work on this.
