Problem with Erlang checkout

[arichiardi]

The ouptup of ./packs/update-live-packs is:

clearing out live packs
creating new live pack dir
copying content from dev packs
cp: cannot stat '/home/kapitan/.emacs.d/packs/dev/lang-pack/vendor/checkouts/otp-erlang-3e8de42/tags.erl': No such file or directory
cp: cannot stat '/home/kapitan/.emacs.d/packs/dev/lang-pack/lib/otp-erlang/tags.erl': No such file or directory
removing dev detritus

Actually it seems like a symlink is missing that points to ../src/tags.erl.

Can I ask if there was a reason for adding it as checkout and not as a submodule?
Would you accept a patch to making it so?

Or maybe I can just remove tags.erl.
