I also had a problem installing with NeoBundle from the Git repository. I have a hunch that it's got to do with the '-' in the first part of the path.
I successfully installed it with the line:
NeoBundle 'repeatable-motions.vim'
This successfully pulls the .zip from vim.org and installs plugin and help without error.
I use:
map <leader>a <Plug>RepeatMostRecentMotion
As generally I just want to repeat the last motion in the same direction.
