I use DropBox to share my .emacs and .emacs.d with the various machines I use. I setup helm using emacs on my mac but now I'm having issues when opening emacs on my Linux box:
Warning (emacs): Unable to activate package `helm'.
Required package `emacs-24' is unavailable
Warning (emacs): Unable to activate package `helm'.
Required package `emacs-24' is unavailable
Warning (initialization): An error occurred while loading `/home/gibson/.emacs':
File error: Cannot open load file, helm
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 also get "Package 'emacs-24' is unavailable" when I try to M-x package-install helm
