HTTPS or Subversion.
I added starter-kit-perl to my list of packages but it does not install.
Warning (initialization): An error occurred while loading `/Users/matthew/.emacs.d/init.el':
error: Package `starter-kit-perl' is not available for installation
To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file. Start Emacs with
the `--debug-init' option to view a complete error backtrace.
I noticed it's not on the marmalade site either... http://marmalade-repo.org/packages?q=starter-kit
