Hi! I thought I'd try to package jekyll, but I've run into some trouble...

I then installed pkgs.bundler_HEAD which also reports the version to be 1.7.9 but does have the --no-install option. However, I got stuck on the next step: $ bundler package --no-install There are no gemspecs at /home/goibhniu/ruby/jekyll. I'm afraid I know very little about ruby or gems etc., so any help/pointers would be appreciated. Thanks! Cillian Now, you'll need to dump the lockfile as a Nix expression.
