Comment (by ryandesign@…):

 Replying to [comment:4 egall@…]:
 > There are many different directories that plugins can be found in, and
 some of them are compatible between Xcode versions, while others aren't. I
 think if we use the `${developer_dir}` variable we should be good though,
 because that already varies between different versions, and I'm pretty
 sure it does it correctly.

 ${developer_dir} can vary within a single OS X version, so binary packages
 could not be shared. Since it's just small text files we could disable
 fetching of archives for these plugin subports.
